Recitals:

     MasTec, its Affiliates party thereto as borrowers, certain financial institutions (the “Original Lenders”) and Fleet Capital Corporation (“FCC”), as Administrative Agent (the “Original Agent”), were parties to a certain Revolving Credit and Security Agreement dated January 22, 2002 (as at any time amended, restated, modified or otherwise supplemented, the “Original Loan Agreement”), pursuant to which the Original Lenders made certain revolving credit loans and letter of credit accommodations to Borrowers.

     Prior to the date of the Existing Loan Agreement (as defined below), (i) FCC assigned all of its interests in the loans under the Original Loan Agreement to Bank of America, N.A., (ii) FCC resigned as Administrative Agent under the Original Loan Agreement and (iii) Bank of America, N.A. was appointed as successor Administrative Agent by the Lenders party to the Original Loan Agreement.

     MasTec, its Affiliates party thereto as borrowers, certain financial institutions (the “Existing Lenders”) and Agent, are parties to a certain Amended and Restated Loan and Security Agreement dated May 10, 2005 (as at any time amended, restated, modified or otherwise supplemented, and as in effect on the date hereof, the “Existing Loan Agreement”), pursuant to which the Existing Lenders made certain revolving credit loans and letter of credit accommodations to Borrowers.

     Borrowers have requested that the Existing Loan Agreement be amended and restated in its entirety to become effective and binding on the Obligors pursuant to the terms hereof, and the Lenders (including the Existing Lenders that are parties hereto) have agreed, subject to the terms of this Agreement, to amend and restate the Existing Loan Agreement in its entirety to read as set forth herein, and it has been agreed by the parties hereto that (a) the commitments which the Existing Lenders that are parties hereto extended to Borrowers under the Existing Loan Agreement and the commitments of new Lenders that become parties hereto shall be extended or advanced upon the amended and restated terms and conditions contained in this Agreement, (b) the Loans and other Secured Obligations outstanding under (and as defined in) the Existing Loan Agreement shall be governed by and deemed to be outstanding under the amended and restated terms and conditions contained herein, and (c) all existing Secured Obligations are and shall continue to be (and all Obligations incurred pursuant hereto shall be) secured by the Loan Documents, which for purposes of this Agreement shall include the Loan Documents under (and as defined in) the Existing Loan Agreement, as such Loan Documents may be now or

hereafter amended, modified, supplemented or restated in connection with the credit facility under this Agreement.

     Obligors have requested that the Lenders establish a revolving credit facility pursuant to which revolving credit loans may be made to Borrowers and letters of credit may be issued for the account of Borrowers, which shall be used by Borrowers to finance their mutual and collective enterprise of providing construction, design, installation, maintenance and upgrade services to providers of telecommunications, broadband, energy services, traffic control and homeland security services. In order to utilize the financial powers of each Borrower in the most efficient and economical manner, and in order to facilitate the financing of each Borrower’s needs, Lenders will, at the request of any Borrower, make loans to all Borrowers under the revolving credit facility on a combined basis and in accordance with the provisions hereinafter set forth. Borrowers’ business is a mutual and collective enterprise and Borrowers believe that the consolidation of all revolving credit loans under this Agreement will enhance the aggregate borrowing powers of each Borrower and ease the administration of their revolving credit loan relationship with Lenders, all to the mutual advantage of Borrowers. Lenders’ willingness to extend credit to Borrowers and to administer each Borrower’s collateral security therefor, on a combined basis as more fully set forth in this Agreement, is done solely as an accommodation to Borrowers and at Borrowers’ request in furtherance of Borrowers’ mutual and collective enterprise.

     Each Borrower has agreed to be liable for loans and all outstanding other obligations under this Agreement and to guarantee the obligations of each of the other Borrowers under this Agreement and each of the other Loan Documents.

     NOW, THEREFORE, for Ten Dollars ($10.00) and other good and valuable consideration, the parties hereto, intending to be bound hereby, agree that the Existing Loan Agreement is hereby amended and restated in its entirety by this Agreement:

               2.1.3. Use of Proceeds. The proceeds of the Revolver Loans shall be used by Borrowers solely for one or more of the following purposes: (i) to satisfy the Debt owing on the Closing Date to the Existing Lenders under the Existing Loan Agreement; (ii) to pay the fees and transaction expenses associated with the closing of the transactions described herein; (iii) to pay any of the Obligations in accordance with this Agreement; (iv) to finance the ongoing working capital and other general corporate purposes of the Borrowers and their Subsidiaries; and (v) to make expenditures for other lawful corporate purposes of Borrowers to the extent such expenditures are not prohibited by this Agreement or Applicable Law. In no event may any Revolver Loan proceeds be used by any Borrower (x) to purchase or to carry, or to reduce, retire or refinance any Debt incurred to purchase or carry, any Margin Stock or for any related purpose that violates the provisions of Regulations T, U or X of the Board of Governors, (y) to fund any operations or finance any investments or activities in, or to make payments to, a Blocked Person, or (z) to defease, redeem or refinance the Senior Notes.

               2.1.4. Revolver Notes. The Revolver Loans made by each Lender and interest accruing thereon shall be evidenced by the records of Agent and such Lender and by the Revolver Note payable to such Lender (or the assignee of such Lender), which shall be executed by Borrowers, completed in conformity with this Agreement and delivered to such Lender. All outstanding principal amounts and accrued interest under the Revolver Notes shall be due and payable as set forth in Section 5.2 hereof.

               2.1.5. Protective Advances. Agent shall be authorized, in its sole and absolute discretion, at any time or times that a Default or Event of Default exists or any of the conditions precedent set forth in Section 11 hereof have not been satisfied, to make Revolver Loans that are Base Rate Loans to Borrowers in an aggregate amount outstanding at any time not to exceed $5,000,000, but only to the extent that Agent, in the exercise of its business judgment, deems the funding of such Loans (herein called “Protective Advances”) to be necessary or desirable (i) to preserve or protect the Collateral or any portion thereof, (ii) to enhance the likelihood, or increase the amount, of repayment of the Obligations or (iii) to pay any other amount chargeable to Borrowers pursuant to the terms of this Agreement, including costs, fees and expenses, all of which Protective Advances shall be deemed part of the Obligations and secured by the Collateral and shall be treated for all purposes of this Agreement (including Sections 5.6.1 and 15.4) as advances for the repayment to Agent and Lenders of Extraordinary Expenses; provided, however, that the Required Lenders may at any time revoke Agent’s authorization to make any such Protective Advances by written notice to Agent, which shall become effective prospectively upon and after Agent’s actual receipt thereof. Absent such revocation, Agent’s determination that the making of a Protective Advance is required for any such purposes shall be conclusive. Each Revolver Lender shall participate in each Protective Advance in an amount equal to its Pro Rata share of the Revolver Commitments. Notwithstanding the foregoing, the maximum amount of Protective Advances outstanding at any time, when added to the aggregate of Revolver Loans, LC Obligations and Out-of-Formula Loans outstanding at such time, shall not exceed the total of the Revolver Commitments. Nothing in this Section 2.1.6 shall be construed to limit in any way the amount of Extraordinary Expenses that may be incurred by Agent and that Borrowers shall be obligated to reimburse to Agent as provided in the Loan Documents.

               2.1.6. Increase in Revolver Commitments.

                    (i) To the extent that any requested increase in the Revolver Commitments is permitted under and will not violate the Indenture, and provided that Agent has received evidence satisfactory to it from Borrowers that such requested increase is permitted under and will not violate the Indenture, then upon the terms and subject to the conditions set forth herein, on any Business Day during the period from July 31, 2007 through the Business Day immediately prior to the last calendar day of the Term, and so long as no Default or Event of Default exists, Borrowers may request that the Revolver

Commitments be increased and, upon such request, Agent shall use reasonable efforts in light of then-current market conditions to solicit additional Eligible Assignees to become Lenders for the purposes of this Agreement, or to encourage any Lender to increase its Revolver Commitment; provided, that (a) each Lender that is a party to this Agreement immediately prior to such increase shall have the first option, and may elect, to fund its Pro Rata share of the amount of the increase in the Revolver Commitment (or any such greater amount in the event that one or more Lenders does not elect to fund its respective Pro Rata share of the amount of the increase in the Revolver Commitment), thereby increasing its Revolver Commitment hereunder, but no Lender shall have any obligation to do so, (b) in the event that it becomes necessary to include a new Eligible Assignee to fund the amount of the requested increase in the Revolver Commitment, each such Eligible Assignee shall become a Lender hereunder and agree to become party to, and shall assume and agree to be bound by, this Agreement, subject to all terms and conditions hereof; (c) no Lender shall have an obligation to Borrowers, Agent or any other Lender to increase its Revolver Commitment or its Pro Rata share of the Revolver Commitments, which decision shall be made in the sole discretion of each Lender; and (d) in no event shall the addition of any Lender or Lenders or the increase in the Revolver Commitment of any Lender under this Section 2.1.6 increase the aggregate Revolver Commitments to an aggregate amount greater than $260,000,000 less the amount of any voluntary reductions under Section 2.2 hereof. Upon the addition of any Lender, or the increase in the Revolver Commitment of any Lender, the dollar amount of the Revolver Commitment set forth opposite each Lender’s name on the signature pages to this Agreement shall be amended by Agent and Borrowers to reflect such addition or such increase, and Agent shall deliver to Lenders and Borrowers a copy of such amendment. Lenders shall be entitled to receive and Borrowers shall be obligated to pay a mutually agreeable amendment fee to Agent for the Pro Rata benefit of those Lenders who increase their Revolver Commitment and any new Lenders, such fee to be based upon the increase in their Revolver Commitments only and not on their aggregate Revolver Commitments after giving effect to such increase.

                    (ii) If any requested increase in the Revolver Commitments is agreed to in accordance with subsection (i) above, Agent and Borrowers shall determine the effective date of such increase (the “Increase Effective Date”). Agent, with the consent and approval of Borrowers, shall promptly confirm in writing to Lenders the final allocation of such increase as of the Increase Effective Date, and each new Lender and each existing Lender that has increased its Revolver Commitment shall purchase Revolver Loans and LC Obligations from each other Lender in an amount such that, after such purchase or purchases, the amount of outstanding Revolver Loans and LC Obligations from each Lender shall equal such Lender’s respective Pro Rata share of the Revolver Commitments, as modified to give effect to such increase, multiplied by the aggregate amount of Revolver Loans outstanding and LC Obligations from all Lenders. As condition precedents to the effectiveness of such increase, Borrowers shall deliver to Agent (i) a certificate dated as of the Increase Effective Date (in sufficient copies for each Lender) signed by the Chief Financial Officer of Borrower Agent on behalf of Borrowers, including a Compliance Certificate demonstrating compliance with the terms of this Agreement and certification that, both before and after giving effect to such increase, each representation and warranty contained in Section 9 and each certification in Section 15.18 of this Agreement is true and correct in all material respects on and as of the Increase Effective Date (except to the extent that any such representation or warranty is stated to relate solely to an earlier date), that the requested increase is permitted under and will not violate the Indenture, and that no Default or Event of Default exists, and (ii) legal opinions from counsel to the Borrowers in form and substance acceptable to Agent that the Loan Agreement and the requested increase in the Revolver Commitments provided for herein is permitted under and does not violate the Indenture or any other Material Contract. Upon the request of any Lender, Borrowers shall deliver a new or amended Revolver Note reflecting the new or increased Revolver Commitment of each such Lender as of the Increase Effective Date.

     2.2. Voluntary Reductions of Revolver Commitments. Borrowers shall have the right to permanently reduce the amount of the Revolver Commitments, on a Pro Rata basis for each Lender, at

any time and from time to time upon written notice to Agent of such reduction, which notice shall specify the amount of such reduction, shall be irrevocable once given, shall be given at least 5 Business Days prior to the end of a month and shall be effective only upon Agent’s receipt thereof. Agent shall promptly transmit such notice to each Lender. The effective date of any voluntary reduction of the Revolver Commitments shall be the first day of the month following the month in which such notice is timely received by Agent. If on the effective date of any such reduction in the Revolver Commitments and after giving effect thereto an Out-of-Formula Condition exists, then the provisions of Section 5.2.1(iii) shall apply, except that such repayment shall be due immediately upon such effective date without further notice to or demand upon Borrowers. If the Commitments are reduced to zero, then such reduction shall be deemed a termination of the Commitments by Borrowers pursuant to Section 6.2.2. The Revolver Commitments, once reduced, may not be reinstated without the written consent of all Lenders.

     2.3. LC Facility.

               2.3.1. Issuance of Letters of Credit. Subject to all of the terms and conditions hereof, Issuing Bank agrees to establish the LC Facility pursuant to which, during the period from the date hereof to (but excluding) the 30th day prior to the last day of the Term, Issuing Bank shall issue one or more Letters of Credit on Borrower Agent’s request therefor from time to time, subject to the following terms and conditions:

               (i) Each Borrower acknowledges that Issuing Bank’s willingness to issue any Letter of Credit is conditioned upon Issuing Bank’s receipt of (A) an LC Application with respect to the requested Letter of Credit and (B) such other instruments and agreements as Issuing Bank may customarily require for the issuance of a letter of credit of equivalent type and amount as the requested Letter of Credit. Issuing Bank shall have no obligation to issue any Letter of Credit unless (x) Issuing Bank receives an LC Request and LC Application at least 3 Business Days prior to the date of issuance of a Letter of Credit, and (y) each of the LC Conditions is satisfied on the date of Issuing Bank’s receipt of the LC Request and at the time of the requested issuance of a Letter of Credit. Any Letter of Credit issued on the Closing Date shall be for an amount in Dollars that is greater than $250,000.

               (ii) Letters of Credit may be requested by a Borrower only if such Letters of Credit are to be used (a) to support obligations of such Borrower incurred in the Ordinary Course of Business of such Borrower, on a standby basis or (b) for such other purposes as Agent and Lenders may approve from time to time in writing.

               (iii) Borrowers shall comply with all of the terms and conditions imposed on Borrowers by Issuing Bank that are contained in any LC Application or in any other agreement customarily or reasonably required by Issuing Bank in connection with the issuance of any Letter of Credit. If Issuing Bank shall honor any request for payment under a Letter of Credit, Borrowers shall pay to Issuing Bank, in Dollars on the first Business Day following the date on which payment was made by Issuing Bank (the “Reimbursement Date”), an amount equal to the amount paid by Issuing Bank under such Letter of Credit, together with interest from and after the Reimbursement Date until Full Payment is made by Borrowers at the Default Rate for Revolver Loans constituting Base Rate Loans. Until Issuing Bank has received payment from Borrowers in accordance with the foregoing provisions of this clause (iii), Issuing Bank, in addition to all of its other rights and remedies under this Agreement and any LC Application, shall be fully subrogated to the rights and remedies of each beneficiary under such Letter of Credit whose claims against Borrowers have been discharged with the proceeds of such Letter of Credit. Whether or not a Borrower submits any Notice of Borrowing to Agent, Borrowers shall be deemed to have requested from Lenders a Borrowing of Base Rate Loans in an amount

necessary to pay to Issuing Bank all amounts due Issuing Bank on any Reimbursement Date and each Lender agrees to fund its Pro Rata share of such Borrowing whether or not any Default or Event of Default has occurred or exists, the Commitments have been terminated, the funding of the Borrowing would result in (or increase the amount of) any Out-of-Formula Condition, or any of the conditions set forth in Section 11 hereof are not satisfied.

               (iv) Borrowers assume all risks of the acts, omissions or misuses of any Letter of Credit by the beneficiary thereof. The obligation of Borrowers to reimburse Issuing Bank for any payment made by Issuing Bank under a Letter of Credit shall be absolute, unconditional, irrevocable and joint and several and shall be paid without regard to any lack of validity or enforceability of any Letter of Credit or the existence of any claim, setoff, defense or other right which Borrowers may have at any time against a beneficiary of any Letter of Credit. In connection with the issuance of any documentary Letter of Credit, none of Agent, Issuing Bank or any Lender shall be responsible for the existence, character, quality, quantity, condition, packing, value or delivery of any goods purported to be represented by any Documents; any differences or variation in the character, quality, quantity, condition, packing, value or delivery of any goods from that expressed in the Documents; the validity, sufficiency or genuineness of any Documents or of any endorsements thereon, even if such Documents should in fact prove to be in any or all respects invalid, insufficient, fraudulent or forged; the time, place, manner or order in which shipment of goods is made; partial or incomplete shipment of, or failure or omission to ship, any or all of the goods referred to in a documentary Letter of Credit or Documents applicable thereto; any deviation from instructions, delay, default or fraud by the shipper and/or any Person in connection with any goods or any shipping or delivery thereof; or any breach of contract between the shipper or vendors and a Borrower. The rights, remedies, powers and privileges of Issuing Bank under this Agreement with respect to Letters of Credit shall be in addition to, and cumulative with, all rights, remedies, powers and privileges of Issuing Bank under any of the LC Documents. Nothing herein shall be deemed to release Issuing Bank from any liability or obligation that it may have in respect to any Letter of Credit arising out of and directly resulting from its own gross negligence or willful misconduct.

               (v) No Letter of Credit shall be extended or amended in any respect that is not solely ministerial, unless all of the LC Conditions are met as though a new Letter of Credit were being requested and issued. With respect to any Letter of Credit that contains any “evergreen” or automatic renewal provision, each Lender shall be deemed to have consented to any such extension or renewal, unless any such Lender shall have provided to Agent written notice that it declines to consent to any such extension or renewal at least 30 days prior to the date on which the Issuing Bank is entitled to decline to extend or renew the Letter of Credit. If all of the LC Conditions are met and no Default or Event of Default exists, no Lender shall have the right to decline to consent to any such extension or renewal.

               (vi) Unless otherwise provided in any of the LC Documents, each LC Application and each standby Letter of Credit shall be subject to the Uniform Customs and Practice for Documentary Credits (1993 Revision), International Chamber of Commerce No. 500, and any amendments or revisions thereto.

Each letter of credit issued or deemed issued and outstanding under the Existing Loan Agreement on the Closing Date, including any extension or renewal thereof (each, an “Existing Letter of Credit”) shall constitute a “Letter of Credit” for all purposes of this Agreement, issued, for purposes of this Section 2.3, on the Closing Date.

               2.3.2. Participations.

               (i) Immediately upon the issuance of any Letter of Credit, each Lender shall be deemed to have irrevocably and unconditionally purchased and received from Issuing Bank, without recourse or warranty, an undivided interest and participation equal to the Pro Rata share of such Lender (a “Participating Lender”) in all LC Obligations arising in connection with such Letter of Credit, but in no event greater than an amount which, when added to such Lender’s Pro Rata share of all Revolver Loans and LC Obligations then outstanding, exceeds such Lender’s Revolver Commitment; provided, however, that if Issuing Bank shall have received written notice from a Lender on or before the Business Day immediately prior to the date of Issuing Bank’s issuance of a Letter of Credit that one or more of the conditions set forth in Section 11 or Section 2.3.1 has not been satisfied, Issuing Bank shall have no obligation to issue the requested Letter of Credit or any other Letter of Credit until such notice is withdrawn in writing by that Lender or until the Required Lenders shall have effectively waived such condition in accordance with this Agreement. In no event shall Issuing Bank be deemed to have notice or knowledge of any existence of any Default or Event of Default or the failure of any conditions in Sections 11 or 2.3.1 hereof to be satisfied prior to its receipt of such notice from a Lender.

               (ii) If Issuing Bank makes any payment under a Letter of Credit and Borrowers do not repay or cause to be repaid the amount of such payment on the Reimbursement Date, Issuing Bank shall promptly notify Agent, which shall promptly notify each Participating Lender, of such payment and each Participating Lender shall promptly (and in any event within 1 Business Day after its receipt of notice from Agent) and unconditionally pay to Agent, for the account of Issuing Bank, in immediately available funds, the amount of such Participating Lender’s Pro Rata share of such payment, and Agent shall promptly pay such amounts to Issuing Bank. If a Participating Lender does not make its Pro Rata share of the amount of such payment available to Agent on a timely basis as herein provided, such Participating Lender agrees to pay to Agent for the account of Issuing Bank, forthwith on demand, such amount together with interest thereon at the Federal Funds Rate until paid. The failure of any Participating Lender to make available to Agent for the account of Issuing Bank such Participating Lender’s Pro Rata share of the LC Obligations shall not relieve any other Participating Lender of its obligation hereunder to make available to Agent its Pro Rata share of the LC Obligations. No Participating Lender shall be responsible for the failure of any other Participating Lender to make available to Agent its Pro Rata share of the LC Obligations on the date such payment is to be made.

               (iii) Whenever Issuing Bank receives a payment on account of the LC Obligations, including any interest thereon, as to which Agent has previously received payments from any Participating Lender for the account of Issuing Bank, Issuing Bank shall promptly pay to each Participating Lender which has funded its participating interest therein, through Agent, in immediately available funds, an amount equal to such Participating Lender’s Pro Rata share thereof.

               (iv) The obligation of each Participating Lender to make payments to Agent for the account of Issuing Bank in connection with Issuing Bank’s payment under a Letter of Credit shall be absolute, unconditional and irrevocable, not subject to any counterclaim, setoff, qualification or exception whatsoever, and shall be made in accordance with the terms and conditions of this Agreement under all circumstances and irrespective of whether or not Borrowers may assert or have any claim for any lack of validity or unenforceability of this Agreement or any of the other Loan Documents; the existence of any Default or Event of Default; any draft, certificate or other document presented under a Letter of Credit having been determined to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; the existence of any setoff or defense any Obligor may have with respect to any of the Obligations; or the termination of the Commitments.

               (v) Neither Issuing Bank nor any of its officers, directors, employees or agents shall be liable to any Participating Lender for any action taken or omitted to be taken under or in connection with any of the LC Documents except as a result of actual gross negligence or willful misconduct on the part of Issuing Bank. Issuing Bank does not assume any responsibility for any failure or delay in performance or breach by a Borrower or any other Person of its obligations under any of the LC Documents. Issuing Bank does not make to Participating Lenders any express or implied warranty, representation or guaranty with respect to the Collateral, the LC Documents, or any Obligor. Issuing Bank shall not be responsible to any Participating Lender for any recitals, statements, information, representations or warranties contained in, or for the execution, validity, genuineness, effectiveness or enforceability of or any of the LC Documents; the validity, genuineness, enforceability, collectibility, value or sufficiency of any of the Collateral or the perfection of any Lien therein; or the assets, liabilities, financial condition, results of operations, business, creditworthiness or legal status of any Obligor or any Account Debtor. In connection with its administration of and enforcement of rights or remedies under any of the LC Documents, Issuing Bank shall be entitled to act, and shall be fully protected in acting upon, any certification, notice or other communication in whatever form believed by Issuing Bank, in good faith, to be genuine and correct and to have been signed, sent or made by a proper Person. Issuing Bank may consult with and employ legal counsel, accountants and other experts and to advise it concerning its rights, powers and privileges under the LC Documents and shall be entitled to act upon, and shall be fully protected in any action taken in good faith reliance upon, any advice given by such experts. Issuing Bank may employ agents and attorneys-in-fact in connection with any matter relating to the LC Documents and shall not be liable for the negligence, default or misconduct of any such agents or attorneys-in-fact selected by Issuing Bank with reasonable care. Issuing Bank shall not have any liability to any Participating Lender by reason of Issuing Bank’s refraining to take any action under any of the LC Documents without having first received written instructions from the Required Lenders to take such action.

               (vi) Upon the request of any Participating Lender, Issuing Bank shall furnish to such Participating Lender copies (to the extent then available to Issuing Bank) of each outstanding Letter of Credit and related LC Documents as may be in the possession of Issuing Bank and reasonably requested from time to time by such Participating Lender.

               2.3.3. Cash Collateral Account. If any LC Obligations, whether or not then due or payable, shall for any reason be outstanding (i) at any time that an Event of Default exists, (ii) on any date an Out-of-Formula Condition exists, (iii) on or at any time after the Commitment Termination Date, or (iv) on the day that is 30 days prior to the last Business Day of the Term, then Borrowers shall, on Issuing Bank’s or Agent’s request, forthwith pay to Issuing Bank the amount of any LC Obligations that are then due and payable and shall, upon the occurrence of any of the events described in clauses (i), (iii) and (iv) hereinabove, Cash Collateralize all outstanding Letters of Credit. If notwithstanding the occurrence of one or more of the events described in clauses (i), (iii) and (iv) in the immediately preceding sentence Borrowers fail to Cash Collateralize any outstanding Letters of Credit on the first Business Day following Agent’s or Issuing Bank’s demand therefor, Lenders may (and shall upon direction of Agent) advance such amount as Revolver Loans (whether or not the Commitment Termination Date has occurred or an Out-of-Formula Condition is created thereby). Such cash (together with any interest accrued thereon) shall be held by Agent in the Cash Collateral Account and may be invested, in Agent’s discretion, in Cash Equivalents. Each Borrower hereby pledges to Agent and grants to Agent a security interest in, for the benefit of Agent in such capacity and for the Pro Rata benefit of Lenders, all Cash Collateral held in the Cash Collateral Account from time to time and all proceeds thereof, as security for the payment of all Obligations (including LC Obligations), whether or not then due or payable. From time to time after cash is deposited in the Cash Collateral Account, Agent may (and shall upon the direction of the Required Lenders) apply Cash Collateral then held in the Cash Collateral Account to the payment of any amounts,

in such order as Agent may elect, as shall be or shall become due and payable by Borrowers to Issuing Bank, Agent or any Lender with respect to the LC Obligations. Neither Borrowers nor any other Person claiming by, through or under or on behalf of Borrowers shall have any right to withdraw any of the Cash Collateral held in the Cash Collateral Account, including any accrued interest, provided that (A) upon termination or expiration of all Letters of Credit and the payment and satisfaction of all of the LC Obligations, or (B) if Agent has confirmed in writing to Borrowers that the events described in clauses (i) or (ii) of the initial sentence of this Section 2.3.3 which required the Cash Collateralization of outstanding Letters of Credit, no longer exist, then any Cash Collateral remaining in the Cash Collateral Account shall be returned to Borrowers unless an Event of Default then exists (in which event Agent may (and shall upon the direction of the Required Lenders) apply such Cash Collateral to the payment of any other Obligations outstanding in accordance with the provisions of Section 5.6, with any surplus to be turned over to Borrowers).

                2.3.4. Indemnifications.

               (i) In addition to any other indemnity which Borrowers may have to any Indemnitees under any of the other Loan Documents and without limiting such other indemnification provisions, each Borrower hereby agrees to indemnify and defend each of the Indemnitees and to hold each of the Indemnitees harmless from and against any and all Indemnified Claims which any Indemnitee may (other than solely as the result of its own gross negligence or willful misconduct or its breach of any of the Loan Documents) incur or be subject to as a consequence, directly or indirectly, of (a) the issuance of, payment or failure to pay or any performance or failure to perform under any Letter of Credit, (b) any suit, investigation or proceeding as to which Agent or any Lender is or may become a party to as a consequence, directly or indirectly, of the issuance of any Letter of Credit or the payment or failure to pay thereunder or (c) Issuing Bank following any instructions of a Borrower with respect to any Letter of Credit or any Document received by Issuing Bank with reference to any Letter of Credit; provided that no Borrower shall be liable to any Indemnitee for any of the foregoing to the extent that they result solely from the willful misconduct or gross negligence of such Indemnitee.

                (ii) Each Participating Lender agrees to indemnify and defend each of the Issuing Bank Indemnitees (to the extent the Issuing Bank Indemnitees are not reimbursed by Borrowers or any other Obligor, but without limiting the indemnification obligations of Borrowers under this Agreement), to the extent of such Lender’s Pro Rata share of the Revolver Commitments, from and against any and all Indemnified Claims which may be imposed on, incurred by or asserted against any of the Issuing Bank Indemnitees in any way related to or arising out of Issuing Bank’s administration or enforcement of rights or remedies under any of the LC Documents or any of the transactions contemplated thereby (including costs and expenses which Borrowers are obligated to pay under Section 15.2 hereof), provided that no Participating Lender shall be liable to any of the Issuing Bank Indemnitees for any of the foregoing to the extent that they result solely from the willful misconduct or gross negligence of such Issuing Bank Indemnitees.

SECTION 3. INTEREST, FEES AND CHARGES

     3.1. Interest.

                3.1.1. Rates of Interest. Borrowers agree to pay interest in respect of all unpaid principal amounts of the Revolver Loans from the respective dates such principal amounts are advanced until paid (whether at stated maturity, on acceleration or otherwise) at a rate per annum equal to the applicable rate indicated below:

               (i) for Revolver Loans made or outstanding as Base Rate Loans, the Applicable Margin plus the Base Rate in effect from time to time; or

               (ii) for Revolver Loans made or outstanding as LIBOR Loans, the Applicable Margin plus the relevant Adjusted LIBOR Rate for the applicable Interest Period selected by Borrowers in conformity with this Agreement.

          Upon determining the Adjusted LIBOR Rate for any Interest Period requested by Borrowers, Agent shall promptly notify Borrowers thereof by telephone and, if so requested by Borrowers, confirm the same in writing. Such determination shall, absent manifest error, be final, conclusive and binding on all parties and for all purposes. The applicable rate of interest for all Loans (or portions thereof) bearing interest based upon the Base Rate shall be increased or decreased, as the case may be, by an amount equal to any increase or decrease in the Base Rate, with such adjustments to be effective as of the opening of business on the day that any such change in the Base Rate becomes effective. Interest on each Loan shall accrue from and including the date on which such Loan is made, converted to a Loan of another Type or continued as a LIBOR Loan to (but excluding) the date of any repayment thereof; provided, however, that, if a Loan is repaid on the same day made, one day’s interest shall be paid on such Loan. The Base Rate on the date hereof is 6.00% per annum and, therefore, the rate of interest in effect hereunder on the date hereof, expressed in simple interest terms, is 6.00% per annum with respect to any portion of the Revolver Loans bearing interest as a Base Rate Loan.

               3.1.2. Conversions and Continuations.

               (i) Borrowers may on any Business Day, subject to the giving of a proper Notice of Conversion/Continuation as hereinafter described, elect (A) to continue all or any part of a LIBOR Loan by selecting a new Interest Period therefor, to commence on the last day of the immediately preceding Interest Period, or (B) to convert all or any part of a Loan of one Type into a Loan of another Type; provided, however, during the period that any Default or Event of Default exists, Agent may (and shall at the direction of the Required Lenders) declare that no Loan may be made or continued as or converted into a LIBOR Loan. Any conversion of a LIBOR Loan into a Base Rate Loan shall be made on the last day of the Interest Period for such LIBOR Loan. Any conversion or continuation made with respect to less than the entire outstanding balance of the Loans must be allocated among Lenders on a Pro Rata basis, and the Interest Period for Loans converted into or continued as LIBOR Loans shall be coterminous for each Lender.

               (ii) Whenever Borrowers desire to convert or continue Loans under Section 3.1.2(i), Borrower Agent shall give Agent written notice (or telephonic notice promptly confirmed in writing) substantially in the form of Exhibit C (a “Notice of Conversion/Continuation”), signed by an authorized officer of Borrower Agent, or in other form required by Agent, at least 1 Business Day before the requested conversion date, in the case of a conversion into Base Rate Loans, and at least 3 Business Days before the requested conversion or continuation date, in the case of a conversion into or continuation of LIBOR Loans. Promptly after receipt of a Notice of Conversion/Continuation, Agent shall notify each Lender in writing of the proposed conversion or continuation. Each such Notice of Conversion/Continuation shall be irrevocable and shall specify the aggregate principal amount of the Loans to be converted or continued, the date of such conversion or continuation (which shall be a Business Day) and whether the Loans are being converted into or continued as LIBOR Loans (and, if so, the duration of the Interest Period to be applicable thereto and, in the absence of any specification by Borrowers of the Interest Period, an Interest Period of one month will be deemed to be specified) or Base Rate Loans. If, upon the expiration of any Interest Period in respect of any LIBOR

Loans, Borrowers shall have failed to deliver the Notice of Conversion/Continuation, Borrowers shall be deemed to have elected to convert such LIBOR Loans to Base Rate Loans.

               3.1.3. Interest Periods. In connection with the making or continuation of, or conversion into, each Borrowing of LIBOR Loans, Borrowers shall select an interest period (each an “Interest Period”) to be applicable to such LIBOR Loan, which interest period shall commence on the date such LIBOR Loan is made and shall end on a numerically corresponding day in the first, second, third or sixth month thereafter; provided, however, that:

               (i) the initial Interest Period for a LIBOR Loan shall commence on the date of such Borrowing (including the date of any conversion from a Loan of another Type) and each Interest Period occurring thereafter in respect of such Revolver Loan shall commence on the date on which the next preceding Interest Period expires;

               (ii) if any Interest Period would otherwise expire on a day that is not a Business Day, such Interest Period shall expire on the next succeeding Business Day, provided that, if any Interest Period in respect of LIBOR Loans would otherwise expire on a day that is not a Business Day but is a day of the month after which no further Business Day occurs in such month, such Interest Period shall expire on the immediately preceding Business Day;

               (iii) any Interest Period that begins on a day for which there is no numerically corresponding day in the calendar month at the end of such Interest Period shall expire on the last Business Day of such calendar month; and

               (v) no Interest Period shall extend beyond the last day of the Term.

               3.1.4. Interest Rate Not Ascertainable. If Agent shall determine (which determination shall, absent manifest error, be final, conclusive and binding upon all parties) that on any date for determining the Adjusted LIBOR Rate for any Interest Period, by reason of any changes arising after the date of this Agreement affecting the London interbank market or any Lender’s position in such market, adequate and fair means do not exist for ascertaining the applicable interest rate on the basis provided for in the definition of Adjusted LIBOR Rate, then, and in any such event, Agent shall forthwith give notice (by telephone promptly confirmed in writing) to Borrowers of such determination. Until Agent notifies Borrowers that the circumstances giving rise to the suspension described herein no longer exist, the obligation of Lenders to make LIBOR Loans shall be suspended, and such affected Loans then outstanding shall, at the end of the then applicable Interest Period or at such earlier time as may be required by Applicable Law, bear the same interest as Base Rate Loans.

               3.1.5. Default Rate of Interest. Borrowers shall pay interest at a rate per annum equal to the Default Rate (i) with respect to the principal amount of any portion of the Obligations (and, to the extent permitted by Applicable Law, all past due interest) that is not paid on the due date thereof (whether due at stated maturity, on demand, upon acceleration or otherwise) until Full Payment; (ii) with respect to the principal amount of all of the Obligations (and, to the extent permitted by Applicable Law, all past due interest) upon the earlier to occur of (x) Borrower Agent’s receipt of notice from Agent of the Required Lenders’ election to charge the Default Rate based upon the existence of any Event of Default (which notice Agent shall send only with the consent or at the direction of the Required Lenders), whether or not acceleration or demand for payment of the Obligations has been made, or (y) the commencement by or against any Borrower of an Insolvency Proceeding whether or not under the circumstances described in clauses (i) or (ii) hereof Lenders elect to accelerate the maturity or demand payment of any of the Obligations; and (iii) with respect to the principal amount of any Out-of-Formula Loans (unless otherwise agreed in writing by the Required Lenders), whether or not demand for payment thereof has

been made by Agent. To the fullest extent permitted by Applicable Law, the Default Rate shall apply and accrue on any judgment entered with respect to any of the Obligations and to the unpaid principal amount of the Obligations during any Insolvency Proceeding of a Borrower. Each Borrower acknowledges that the cost and expense to Agent and each Lender attendant upon the occurrence of an Event of Default are difficult to ascertain or estimate and that the Default Rate is a fair and reasonable estimate to compensate Agent and Lenders for such added cost and expense. Interest accrued at the Default Rate shall be due and payable on demand.

     3.2. Fees. In consideration of Lenders’ establishment of the Commitments in favor of Borrowers, and Agent’s agreement to serve as collateral and administrative agent hereunder, Borrowers agree to pay the following fees:

               3.2.1. Unused Line Fee. Borrowers shall pay to Agent for the Pro Rata benefit of Lenders a fee equal to (i) 0.375% per annum of the amount by which the Average Revolver Loan Balance for any month (or portion thereof that the Commitments are in effect) is less than the aggregate amount of the Revolver Commitments; provided that if the Average Revolver Loan Balance for the immediately preceding Fiscal Quarter (or portion thereof) is greater than 50% of the aggregate amount of the Revolver Commitments, then such fee shall be 0.250% per annum of the amount by which the Average Revolver Loan Balance for such month (or portion thereof) is less than the aggregate amount of the Revolver Commitments, in each case such fee to be paid on the first day of the following month, provided that, if the Commitments are terminated on a day other than the first day of a month, then any such fee payable for the month in which termination occurs shall be paid on the effective date of such termination.

               3.2.2. LC Facility Fees. Borrowers shall pay: (a)(i) to Agent, for the Pro Rata account of each Lender for all Letters of Credit, the Applicable Margin in effect for Revolver Loans that are LIBOR Loans on a per annum basis based on the average amount available to be drawn under Letters of Credit outstanding and all Letters of Credit that are paid or expire during the period of measurement (or, with respect to each Letter of Credit that is secured by cash deposited by Borrowers into the Cash Collateral Account on terms satisfactory to Agent, 0.65% on a per annum basis based on the average amount available to be drawn under all such cash-collateralized Letters of Credit outstanding and all such cash-collateralized Letters of Credit that are paid or expire during the period of measurement), in each case payable monthly, in arrears, on the first Business Day of the following month; (ii) to Agent, for its own account a Letter of Credit fronting fee of 0.125% per annum based on the average amount available to be drawn under all Letters of Credit outstanding and all Letters of Credit that are paid or expire during the period of measurement, payable monthly, in arrears, on the first Business Day of the following month; and (iii) to Issuing Bank for its own account all customary charges associated with the issuance, amending, negotiating, payment, processing and administration of all Letters of Credit.

               3.2.3. Audit and Appraisal Fees and Expenses. Borrowers shall reimburse Agent for all reasonable costs and expenses incurred by Agent (including standard fees charged by Agent’s internal appraisal department) in connection with (i) examinations and reviews of any Obligor’s books and records and such other matters pertaining to any Obligor or any Collateral as Agent shall deem appropriate in the exercise of its reasonable credit judgment, up to three (3) times per Loan Year, unless a Default or Event of Default exists (in which event, there shall be no limit on the number of examinations and reviews for which Borrowers shall be obligated to reimburse Agent) and, in each case, shall pay to Agent the standard amount charged by Agent per day ($850 per day as of the Closing Date) for each day that an employee or agent of Agent shall be engaged in an examination or review of any Obligor’s books and records, (ii) appraisals of Equipment no more frequently than three (3) times per Loan Year (one of which may be a full physical appraisal and the other two of which shall be desktop appraisals performed by employees or agents of Agent), and (iii) appraisals of Eligible Real Estate no more frequently than one (1) time per Loan Year; provided, that, in the case of each of clauses (ii) and (iii), if a Default or

Event of Default exists, there shall be no limit on the number or type of appraisals for which Borrowers shall be obligated to reimburse Agent.

               3.2.4. Other Fees. Borrowers shall pay to Agent the fees in the amounts and on the dates as provided in the Fee Letter.

               3.2.5. General Provisions. All fees shall be fully earned by the identified recipient thereof pursuant to the foregoing provisions of this Agreement on the due date thereof (and, in the case of Letters of Credit, upon each issuance, renewal or extension of such Letter of Credit) and, except as otherwise set forth herein or required by Applicable Law, shall not be subject to rebate, refund or proration. All fees provided for in Section 3.2 are and shall be deemed to be compensation for services and are not, and shall not be deemed to be, interest or any other charge for the use, forbearance or detention of money.

     3.3. Computation of Interest and Fees. All fees and other charges provided for in this Agreement that are calculated as a per annum percentage of any amount and all interest shall be calculated daily and shall be computed on the actual number of days elapsed over a year of 360 days. For purposes of computing interest and other charges hereunder, each Payment Item and other form of payment received by Agent shall be deemed applied by Agent on account of the Obligations (subject to final payment of such items) on the first Business Day after the Business Day on which Agent receives such Payment Item in the Payment Account, and Agent shall be deemed to have received such Payment Item on the date specified in Section 5.7 hereof. Each determination by Agent of interest and fees hereunder shall be made in good faith and, except for manifest error, shall be presumptive evidence of the correctness of such interest and fees.

     3.4. Reimbursement Obligations.

               3.4.1. Borrowers shall reimburse Agent and (during any period that an Event of Default exists) each Lender for all legal, accounting, appraisal, consulting and other fees and expenses incurred by Agent or any Lender in connection with: (i) the negotiation and preparation of any of the Loan Documents, any amendment or modification thereto, any waiver of any Default or Event of Default thereunder, or any restructuring or forbearance with respect thereto; (ii) the administration of the Loan Documents and the transactions contemplated thereby; (iii) action taken to perfect or maintain the perfection or priority of any of Agent’s Liens with respect to any of the Collateral; (iv) any inspection of or audits conducted by Agent with respect to any Borrower’s books and records or any of the Collateral; (v) any effort by Agent to verify, protect, appraise, preserve, or restore any of the Collateral or to collect, sell, liquidate or otherwise dispose of or realize upon any of the Collateral; (vi) any litigation, contest, dispute, suit, proceeding or action (whether instituted by or against Agent, any Lender, any Obligor or any other Person) in any way arising out of or relating to any of the Collateral (or the validity, perfection or priority of any of Agent’s Liens thereon), any of the Loan Documents or the validity, allowance or amount of any of the Obligations; (vii) the protection or enforcement or any rights or remedies of Agent in, and the monitoring of, any Insolvency Proceeding; and (viii) any other action taken by Agent or any Lender to enforce any of the rights or remedies of Agent against any Obligor or Account Debtor or to enforce collection of any of the Obligations or payments with respect to any of the Collateral. All amounts chargeable to Borrowers under this Section 3.4 shall constitute Obligations that are secured by all of the Collateral and shall be payable on demand to Agent. Borrowers shall also reimburse Agent for expenses incurred by Agent in its administration of any of the Collateral to the extent and in the manner provided in Section 8 hereof or in any of the other Loan Documents. The foregoing shall be in addition to, and shall not be construed to limit, any other provision of any of the Loan Documents

regarding the reimbursement by Borrowers of costs, expenses or liabilities suffered or incurred by Agent or any Lender.

          3.4.2. If at any time Agent or (with the prior consent of Agent) any Lender shall agree to indemnify any Person against losses or damages that such Person may suffer or incur in its dealings or transactions with Borrowers, or shall guarantee or otherwise assure payment of any liability or obligation of Borrowers to such Person, or otherwise shall provide assurances of Borrowers’ payment or performance under any agreement with such Person, including indemnities, guaranties or other assurances of payment or performance given by Agent or any Lender with respect to Banking Relationship Debt, then the Contingent Obligation of Agent or any Lender providing any such indemnity, guaranty or other assurance of payment or performance, together with any payment made or liability incurred by Agent or any Lender in connection therewith, shall constitute Obligations that are secured by the Collateral and Borrowers shall repay, on demand, any amount so paid or any liability incurred by Agent or any Lender in connection with any such indemnity, guaranty or assurance. Nothing herein shall be construed to impose upon Agent or any Lender any obligation to provide any such indemnity, guaranty or assurance. The foregoing agreement of Borrowers shall apply whether or not such indemnity, guaranty or assurance is in writing or oral and regardless of any Borrower’s knowledge of the existence thereof, shall survive termination of the Commitments and Full Payment of the Obligations and any other provisions of the Loan Documents regarding reimbursement or indemnification by Borrowers of costs, expenses or liabilities suffered or incurred by Agent or any Lender. Agent will endeavor to provide notice to Borrowers of any such indemnity, guaranty or assurance if the applicable Borrower is not otherwise a party thereto; provided, that, Agent’s failure to so notify any Borrower shall not result in any liability to Agent or any Lender or in any way condition Agent’s or any Lender’s right to repayment or reimbursement hereunder.

     3.5. Bank Charges. Borrowers shall pay to Agent, on demand, any and all fees, costs or expenses which Agent pays to a bank or other similar institution (including any fees paid by Agent or any Lender to any Participant) arising out of or in connection with (i) the forwarding to a Borrower or any other Person on behalf of Borrower by Agent of proceeds of Loans made by Lenders to a Borrower pursuant to this Agreement and (ii) the depositing for collection by Agent of any Payment Item received or delivered to Agent on account of the Obligations. Each Borrower acknowledges and agrees that Agent may charge such costs, fees and expenses to Borrowers based upon Agent’s good faith estimate of such costs, fees and expenses as they are incurred by Agent.

     3.6. Illegality. Notwithstanding anything to the contrary contained elsewhere in this Agreement, if (i) any change in any law or regulation or in the interpretation thereof by any Governmental Authority charged with the administration thereof shall make it unlawful for a Lender to make or maintain a LIBOR Loan or to give effect to its obligations as contemplated hereby with respect to a LIBOR Loan or (ii) at any time such Lender determines that the making or continuance of any LIBOR Loan has become impracticable as a result of a contingency occurring after the date hereof which adversely affects the London interbank market or the position of such Lender in such market, then such Lender shall give after such determination Agent and Borrowers notice thereof and may thereafter (1) declare that LIBOR Loans will not thereafter be made by such Lender, whereupon any request by a Borrower for a LIBOR Loan from such Lender shall be deemed a request for a Base Rate Loan unless such Lender’s declaration shall be subsequently withdrawn (which declaration shall be withdrawn promptly after the cessation of the circumstances described in clause (i) or (ii) above); and (2) require that all outstanding LIBOR Loans made by such Lender be converted to Base Rate Loans, under the circumstances of clause (i) or (ii) of this Section 3.6 insofar as such Lender determines the continuance of LIBOR Loans to be impracticable, in which event all such LIBOR Loans of such Lender shall be

converted automatically to Base Rate Loans as of the date of any Borrower’s receipt of the aforesaid notice from such Lender.

     3.7. Increased Costs. If, by reason of (a) the introduction after the date hereof of or any change (including any change by way of imposition or increase of Statutory Reserves or other reserve requirements) in or in the interpretation of any law or regulation, or (b) the compliance with any guideline or request from any central bank or other Governmental Authority or quasi-Governmental Authority exercising control over banks or financial institutions generally (whether or not having the force of law):

               (i) any Lender shall be subject after the date hereof to any Tax, duty or other charge with respect to any LIBOR Loan or Letter of Credit or its obligation to make LIBOR Loans or to issue Letters of Credit or participate in the LC Obligations arising from the issuance of Letters of Credit, or a change shall result in the basis of taxation of payment to any Lender of the principal of or interest on its LIBOR Loans or its obligation to make LIBOR Loans, issue Letters of Credit or participate in the LC Obligations arising from the issuance of Letters of Credit (except for changes in the rate of Tax on the overall net income or gross receipts or franchise tax of such Lender imposed by the jurisdiction in which such Lender’s principal executive office is located); or

               (ii) any reserve (including any imposed by the Board of Governors), special deposits or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender shall be imposed or deemed applicable or any other condition affecting its LIBOR Loans or Letters of Credit or its obligation to make LIBOR Loans or to issue Letters of Credit or participate in the LC Obligations arising from the issuance of Letters of Credit shall be imposed on such Lender or the London interbank market;

and as a result thereof there shall be any increase in the cost to such Lender of agreeing to make or making, funding or maintaining LIBOR Loans or issuing Letters of Credit (except to the extent already included in the determination of the applicable Adjusted LIBOR Rate for LIBOR Loans), or there shall be a reduction in the amount received or receivable by such Lender, then such Lender shall, promptly after determining the existence or amount of any such increased costs for which such Lender seeks payment hereunder, give any Borrower notice thereof and Borrowers shall from time to time, upon written notice from and demand by such Lender (with a copy of such notice and demand to Agent), pay to Agent for the account of such Lender, within 5 Business Days after the date specified in such notice and demand, an additional amount sufficient to indemnify such Lender against such increased costs. A certificate as to the amount of such increased costs, submitted to Borrowers by such Lender, shall be final, conclusive and binding for all purposes, absent manifest error.

     If any Lender shall advise Agent at any time that, because of the circumstances described hereinabove in this Section 3.7 or any other circumstances arising after the date of this Agreement affecting such Lender or the London interbank market or such Lender’s or BofA’s position in such market, the Adjusted LIBOR Rate, as determined by Agent, will not adequately and fairly reflect the cost to such Lender of funding LIBOR Loans or issuing Letters of Credit, then, and in any such event:

               (i) Agent shall forthwith give notice (by telephone confirmed promptly in writing) to Borrowers and Lenders of such event;

               (ii) Borrowers’ right to request and such Lender’s obligation to make LIBOR Loans or to issue Letters of Credit or participate in the LC Obligations arising from the issuance of Letters of Credit shall be immediately suspended and Borrowers’ right to continue a LIBOR Loan as such beyond the then applicable Interest Period or to request a Letter of Credit shall also

be suspended, until each condition giving rise to such suspension no longer exists; and

               (iii) such Lender shall make a Base Rate Loan as part of the requested Borrowing of LIBOR Loans, which Base Rate Loan shall, for all purposes, be considered part of such Borrowing.

     For purposes of this Section 3.7, all references to a Lender shall be deemed to include any bank holding company or bank parent of such Lender. If any Lender provides notice that, due to the circumstances described in this Section 3.7, the Adjusted LIBOR Rate will not adequately and fairly reflect the cost to such Lender of funding LIBOR Loans or participating in LC Obligations arising from the issuance of Letters of Credit, then such Lender may be replaced pursuant to the provisions of Section 13.17.

     3.8. Capital Adequacy. If any Lender determines that (i) the introduction after the date hereof of any Capital Adequacy Regulation, (ii) any change in any Capital Adequacy Regulation, (iii) any change in the interpretation or administration of any Capital Adequacy Regulation by any central bank or other Governmental Authority charged with the interpretation or administration thereof, or (iv) compliance by such Lender or any corporation or other entity controlling such Lender with any Capital Adequacy Regulation, affects or would affect the amount of capital required or expected to be maintained by such Lender or any corporation or other entity controlling such Lender and (taking into consideration such Lender’s or such corporation’s or other entity’s policies with respect to capital adequacy and such Lender’s desired return on capital) determines that the amount of such capital is increased as a consequence of its Commitments, loans, credits or obligations under this Agreement, then: (a) Agent shall promptly, after its receipt of a certificate from such Lender setting forth such Lender’s determination of such occurrence, give notice thereof to Borrowers and Lenders; and (b) Borrowers shall pay to Agent, for the account of such Lender, as an additional fee from time to time, on demand, such amount as such Lender certifies to be the amount reasonably calculated to compensate such Lender for such reduction. A certificate of such Lender claiming entitlement to compensation as set forth above will be conclusive in the absence of manifest error. Such certificate will set forth the nature of the occurrence giving rise to such compensation, the additional amount or amounts to be paid to such Lender (including the basis for such Lender’s determination of such amount), and the method by which such amounts were determined. In determining such amount, such Lender may use any reasonable averaging and attribution method. For purposes of this Section 3.8 all references to a Lender shall be deemed to include any bank holding company or bank parent of such Lender.

     3.9. Mitigation. Each Lender agrees that, with reasonable promptness after such Lender becomes aware that such Lender is entitled to receive payments under Section 3.6, 3.7 or 3.8, or is or has become subject to U.S. withholding taxes payable by any Borrower in respect of its Loans, it will, to the extent not inconsistent with any internal policy of such Lender or any applicable legal or regulatory restriction, (i) use all reasonable efforts to make, fund or maintain the Commitment of such Lender or the Loans of such Lender through another lending office of such Lender, or (ii) take such other reasonable measures, if, as a result thereof, the circumstances which would relieve Borrowers from their obligations to pay such additional amounts (or reduce the amount of such payments), or such withholding taxes would be reduced, and if the making, funding or maintaining of such Commitment or Loans through such other lending office or in accordance with such other measures, as the case may be, would not otherwise adversely affect such Commitment or Loans or the interests of such Lender.

     3.10. Funding Losses. If for any reason (other than due to a default by a Lender or as a result of a Lender’s refusal to honor a LIBOR Loan request due to circumstances described in this Agreement) a Borrowing of, or conversion to or continuation of, LIBOR Loans does not occur on the date specified therefor in a Notice of Borrowing or Notice of Conversion/Continuation (whether or not withdrawn), or if

any repayment (including any conversions pursuant to Section 3.1.2) of any of its LIBOR Loans occurs on a date that is not the last day of an Interest Period applicable thereto, or if for any reason Borrowers default in their obligation to repay LIBOR Loans when required by the terms of this Agreement, then Borrowers shall pay to Agent an administrative fee of $150 and to each Lender an amount equal to all losses and expenses which such Lender may sustain or incur as a consequence thereof, including any such loss or expense arising from the liquidation or redeployment of funds obtained by it to maintain its LIBOR Loans or from fees payable to terminate the deposits from which such funds were obtained. Borrowers shall pay all such amounts due to any Lender upon presentation by such Lender of a statement setting forth the amount and such Lender’s calculation thereof, which statement shall be deemed true and correct absent manifest error. For purposes of this Section 3.10, all references to a Lender shall be deemed to include any bank holding company or bank parent of such Lender.

     3.11. Maximum Interest. Regardless of any provision contained in any of the Loan Documents, in no contingency or event whatsoever shall the aggregate of all amounts that are contracted for, charged or received by Agent and Lenders pursuant to the terms of this Agreement or any of the other Loan Documents and that are deemed interest under Applicable Law exceed the highest rate permissible under any Applicable Law. No agreements, conditions, provisions or stipulations contained in this Agreement or any of the other Loan Documents or the exercise by Agent of the right to accelerate the payment or the maturity of all or any portion of the Obligations, or the exercise of any option whatsoever contained in any of the Loan Documents, or the prepayment by Borrowers of any of the Obligations, or the occurrence of any contingency whatsoever, shall entitle Agent or any Lender to charge or receive in any event, interest or any charges, amounts, premiums or fees deemed interest by Applicable Law (such interest, charges, amounts, premiums and fees referred to herein collectively as “Interest”) in excess of the Maximum Rate and in no event shall Borrowers be obligated to pay Interest exceeding such Maximum Rate, and all agreements, conditions or stipulations, if any, which may in any event or contingency whatsoever operate to bind, obligate or compel Borrowers to pay Interest exceeding the Maximum Rate shall be without binding force or effect, at law or in equity, to the extent only of the excess of Interest over such Maximum Rate. If any Interest is charged or received with respect to the Obligations in excess of the Maximum Rate (“Excess”), each Borrower stipulates that any such charge or receipt shall be the result of an accident and bona fide error, and such Excess, to the extent received, shall be applied first to reduce the principal of such Obligations and the balance, if any, returned to Borrowers, it being the intent of the parties hereto not to enter into a usurious or otherwise illegal relationship. The right to accelerate the maturity of any of the Obligations does not include the right to accelerate any Interest that has not otherwise accrued on the date of such acceleration, and Agent and Lenders do not intend to collect any unearned Interest in the event of any such acceleration. Each Borrower recognizes that, with fluctuations in the rates of interest set forth in Section 3.1.1 of this Agreement or in the Notes, and the Maximum Rate, such an unintentional result could inadvertently occur. All monies paid to Agent or any Lender hereunder or under any of the other Loan Documents, whether at maturity or by prepayment, shall be subject to any rebate of unearned Interest as and to the extent required by Applicable Law. By the execution of this Agreement, each Borrower covenants that (i) the credit or return of any Excess shall constitute the acceptance by such Borrower of such Excess, and (ii) such Borrower shall not seek or pursue any other remedy, legal or equitable, against Agent or any Lender, based in whole or in part upon contracting for, charging or receiving any Interest in excess of the Maximum Rate. For the purpose of determining whether or not any Excess has been contracted for, charged or received by Agent or any Lender, all Interest at any time contracted for, charged or received from Borrowers in connection with any of the Loan Documents shall, to the extent permitted by Applicable Law, be amortized, prorated, allocated and spread in equal parts throughout the full term of the Obligations. Borrowers, Agent and Lenders shall, to the maximum extent permitted under Applicable Law, (i) characterize any non-principal payment as an expense, fee or premium rather than as Interest and (ii) exclude voluntary prepayments and the effects thereof. The provisions of this Section 3.11 shall be deemed to be incorporated into every Loan Document (whether or not any provision of this Section is

referred to therein). All such Loan Documents and communications relating to any Interest owed by Borrowers and all figures set forth therein shall, for the sole purpose of computing the extent of Obligations, be automatically recomputed by Borrowers, and by any court considering the same, to give effect to the adjustments or credits required by this Section 3.11.

SECTION 4. LOAN ADMINISTRATION

     4.1. Manner of Borrowing and Funding Revolver Loans. Borrowings under the Commitments established pursuant to Section 2.1 hereof shall be made and funded as follows:

               4.1.1. Notice of Borrowing.

               (i) Whenever Borrowers desire to make a Borrowing under Section 2.1 of this Agreement (other than a Borrowing resulting from a conversion or continuation pursuant to Section 3.1.2), Borrowers shall give Agent prior written notice (or telephonic notice promptly confirmed in writing) of such Borrowing request (a “Notice of Borrowing”), which shall be in the form of Exhibit D annexed hereto and signed by an authorized officer of Borrower Agent. Such Notice of Borrowing shall be given by Borrower Agent no later than 12:00 noon at the office designated by Agent from time to time (a) on the Business Day of the requested funding date of such Borrowing, in the case of Base Rate Loans, and (b) at least 2 Business Days prior to the requested funding date of such Borrowing, in the case of LIBOR Loans. Notices received after 12:00 noon shall be deemed received on the next Business Day. The Revolver Loans made by each Lender on the Closing Date shall be in excess of $250,000 and shall be made as Base Rate Loans and thereafter may be made or continued as or converted into Base Rate Loans or LIBOR Loans. Each Notice of Borrowing (or telephonic notice thereof) shall be irrevocable and shall specify (a) the principal amount of the Borrowing, (b) the date of Borrowing (which shall be a Business Day), (c) whether the Borrowing is to consist of Base Rate Loans or LIBOR Loans, (d) in the case of LIBOR Loans, the duration of the Interest Period to be applicable thereto, and (e) the account of Borrowers to which the proceeds of such Borrowing are to be disbursed.

               (ii) Unless payment is otherwise timely made by Borrowers, the becoming due of any amount required to be paid with respect to any of the Obligations (whether as principal, accrued interest, fees or other charges, including the repayment of any LC Obligations, and any amounts owed to any Affiliate of Agent) shall be deemed irrevocably to be a request by Borrower Agent (without any requirement for the submission of a Notice of Borrowing) for Revolver Loans on the due date of, and in an aggregate amount required to pay, such Obligations, and the proceeds of such Revolver Loans may be disbursed by way of direct payment of the relevant Obligation and shall bear interest as Base Rate Loans. Neither Agent nor any Lender shall have any obligation to Borrowers to honor any deemed request for a Revolver Loan on or after the Commitment Termination Date, when an Out-of-Formula Condition exists or would result therefrom, or when any applicable condition precedent set forth in Section 11 hereof is not satisfied, but may do so in the discretion of Agent (or at the direction of the Required Lenders) and without regard to the existence of, and without being deemed to have waived, any Default or Event of Default and regardless of whether such Revolver Loan is funded after the Commitment Termination Date.

               (iii) If Borrowers elect to establish a Controlled Account with BofA or any Affiliate of BofA, then the presentation for payment by Bank of any check or other item of payment drawn on the Controlled Account at a time when there are insufficient funds in such account to cover such check shall be deemed irrevocably to be a request by Borrower Agent (without any requirement for the submission of a Notice of Borrowing) for Revolver Loans on

the date of such presentation and in an amount equal to the aggregate amount of the items presented for payment, and the proceeds of such Revolver Loans may be disbursed to the Controlled Account and shall bear interest as Base Rate Loans. Neither Agent nor any Lender shall have any obligation to honor any deemed request for a Revolver Loan on or after the Commitment Termination Date or when an Out-of-Formula Condition exists or would result therefrom or when any condition precedent in Section 11 hereof is not satisfied, but may do so in the discretion of Agent (or at the direction of the Required Lenders) and without regard to the existence of, and without being deemed to have waived, any Default or Event of Default and regardless of whether such Revolver Loan is funded after the Commitment Termination Date.

               4.1.2. Fundings by Lenders. Subject to its receipt of notice from Agent of a Notice of Borrowing as provided in Section 4.1.1(i) (except in the case of a deemed request by Borrower Agent for a Revolver Loan as provided in Sections 4.1.1(ii) or (iii) or 4.1.3(ii) hereof, in which event no Notice of Borrowing need be submitted), each Lender shall timely honor its Revolver Commitment by funding its Pro Rata share of each Borrowing of Revolver Loans that is properly requested and that Borrowers are entitled to receive under the Loan Agreement. Agent shall notify Lenders of each Notice of Borrowing (or deemed request for a Borrowing pursuant to Section 4.1.1(ii) or (iii) hereof), by 1:00 p.m. on the proposed funding date (in the case of Base Rate Loans) or by 1:00 p.m. at least 2 Business Days before the proposed funding date (in the case of LIBOR Loans). Each Lender shall deposit with Agent an amount equal to its Pro Rata share of the Borrowing requested or deemed requested by Borrowers at Agent’s designated bank in immediately available funds not later than 3:00 p.m. on the date of funding of such Borrowing, unless Agent’s notice to Lenders is received after 1:00 p.m. on the proposed funding date of a Base Rate Loan, in which event Lenders shall deposit with Agent their respective Pro Rata shares of the requested Borrowing on or before 11:00 a.m. of the next Business Day. Subject to its receipt of such amounts from Lenders, Agent shall make the proceeds of the Revolver Loans received by it available to Borrowers by disbursing such proceeds in accordance with Borrower Agent’s disbursement instructions set forth in the applicable Notice of Borrowing. Neither Agent nor any Lender shall have any liability on account of any delay by any bank or other depository institution in treating the proceeds of any Revolver Loan as collected funds or any delay in receipt, or any loss, of funds that constitute a Revolver Loan, the wire transfer of which was initiated by Agent in accordance with wiring instructions provided to Agent. Unless Agent shall have been notified in writing by a Lender prior to the proposed time of funding that such Lender does not intend to deposit with Agent an amount equal such Lender’s Pro Rata share of the requested Borrowing (or deemed request for a Borrowing pursuant to Section 4.1.1(ii) or (iii) hereof), Agent may assume that such Lender has deposited or promptly will deposit its share with Agent and Agent may in its discretion disburse a corresponding amount to Borrowers on the applicable funding date. If a Lender’s Pro Rata share of such Borrowing is not in fact deposited with Agent, then, if Agent has disbursed to Borrowers an amount corresponding to such share, then such Lender agrees to pay, and in addition Borrowers agree to repay, to Agent forthwith on demand such corresponding amount, together with interest thereon, for each day from the date such amount is disbursed by Agent to or for the benefit of Borrowers until the date such amount is paid or repaid to Agent, (a) in the case of Borrowers, at the interest rate applicable to such Borrowing and (b) in the case of such Lender, at the Federal Funds Rate. If such Lender repays to Agent such corresponding amount, such amount so repaid shall constitute a Revolver Loan, and if both such Lender and Borrowers shall have repaid such corresponding amount, Agent shall promptly return to Borrowers such corresponding amount in same day funds. A notice from Agent submitted to any Lender with respect to amounts owing under this Section 4.1.2 shall be conclusive, absent manifest error.

               4.1.3. Settlement and Swingline Loans.

               (i) In order to facilitate the administration of the Revolver Loans under this Agreement, Lenders and Agent agree (which agreement shall be solely between Lenders and

Agent and shall not be for the benefit of or enforceable by any Borrower) that settlement among them with respect to the Revolver Loans may take place on a periodic basis on dates determined from time to time by Agent (each a “Settlement Date”), which may occur before or after the occurrence or during the continuance of a Default or Event of Default and whether or not all of the conditions set forth in Section 11 have been met. On each Settlement Date, payment shall be made by or to each Lender in the manner provided herein and in accordance with the Settlement Report delivered by Agent to Lenders with respect to such Settlement Date so that, as of each Settlement Date and after giving effect to the transaction to take place on such Settlement Date, each Lender shall hold its Pro Rata share of all Revolver Loans and participations in LC Obligations. Agent shall request settlement with the Lenders on a basis not less frequently than once every 5 Business Days.

               (ii) Between Settlement Dates, Agent may request BofA to advance, and BofA may, but shall in no event be obligated to, advance to Borrowers out of BofA’s own funds the entire principal amount of any Borrowing of Revolver Loans that are Base Rate Loans requested or deemed requested pursuant to this Agreement (any such Revolver Loan funded exclusively by BofA being referred to as a “Swingline Loan”). Each Swingline Loan shall constitute a Revolver Loan hereunder and shall be subject to all of the terms, conditions and security applicable to other Revolver Loans, except that all payments thereon shall be payable to BofA solely for its own account and all Swingline Loans shall be made as Base Rate Loans plus the Applicable Margin then in effect for Revolver Loans and shall not be entitled to be converted into LIBOR Loans. The obligation of Borrowers to repay such Swingline Loans to BofA shall be evidenced by the records of BofA and need not be evidenced by any promissory note. Unless a funding is required by all Lenders pursuant to Sections 2.1.5 or 13.9.4, Agent shall not request BofA to make any Swingline Loan if (A) Agent shall have received written notice from any Lender that one or more of the applicable conditions precedent set forth in Section 11 hereof will not be satisfied on the requested funding date for the applicable Borrowing and Agent has made a determination (without any liability to any Person) that such condition precedent will not be satisfied, (B) the requested Borrowing would exceed the amount of Availability on the funding date or (C) the aggregate amount of all Swingline Loans outstanding when added to the amount of the requested Borrowing, would exceed $20,000,000. BofA shall not be required to determine whether the applicable conditions precedent set forth in Section 11 hereof have been satisfied or the requested Borrowing would exceed the amount of Availability on the funding date applicable thereto prior to making, in its sole discretion, any Swingline Loan. On each Settlement Date, or, if earlier, upon demand by Agent for payment thereof, the then outstanding Swingline Loans shall be immediately due and payable. As provided in Section 3.1.1(ii), Borrowers shall be deemed to have requested (without the necessity of submitting any Notice of Borrowing) Revolver Loans to be made on each Settlement Date in the amount of all outstanding Swingline Loans and to have Agent cause the proceeds of such Revolver Loans to be applied to the repayment of such Swingline Loans and interest accrued thereon. Agent shall notify the Lenders of the outstanding balance of Revolver Loans prior to 1:00 p.m. on each Settlement Date and each Lender (other than BofA) shall deposit with Agent (without setoff, counterclaim or reduction of any kind) an amount equal to its Pro Rata share of the amount of Revolver Loans deemed requested in immediately available funds not later than 3:00 p.m. on such Settlement Date. Each Lender’s obligation to make such deposit with Agent shall be absolute and unconditional, without defense, offset, counterclaim or other defense, and without regard to whether any of the conditions precedent set forth in Section 11 hereof are satisfied, any Out-of-Formula Condition exists or the Commitment Termination Date has occurred. If, as the result of the commencement by or against Borrowers of any Insolvency Proceeding or otherwise, any Swingline Loan may not be repaid by the funding by Lenders of Revolver Loans, then each Lender (other than BofA) shall be deemed to have purchased a participating interest in any unpaid Swingline Loan in an amount equal to

such Lender’s Pro Rata share of such Swingline Loan and shall transfer to BofA, in immediately available funds not later than the second Business Day after BofA’s request therefor, the amount of such Lender’s participation. The proceeds of Swingline Loans may be used solely for purposes for which Revolver Loans generally may be used in accordance with Section 2.1.3 hereof. If any amounts received by BofA in respect of any Swingline Loans are later required to be returned or repaid by BofA to Borrowers or any other Obligor or their respective representatives or successors-in-interest, whether by court order, settlement or otherwise, the other Lenders shall, upon demand by BofA with notice to Agent, pay to Agent for the account of BofA, an amount equal to each other Lender’s Pro Rata share of all such amounts required to be returned or repaid.

               4.1.4. Disbursement Authorization. Each Borrower hereby irrevocably authorizes Agent to disburse the proceeds of each Revolver Loan requested by any Borrower, or deemed to be requested pursuant to Section 4.1.1 or Section 4.1.3(ii), as follows: (i) the proceeds of each Revolver Loan requested under Section 4.1.1(i) shall be disbursed by Agent in accordance with the terms of the written disbursement letter from Borrowers in the case of the initial Borrowing, and, in the case of each subsequent Borrowing, by wire transfer to such bank account of Borrowers as may be agreed upon by Borrowers and Agent from time to time or elsewhere if pursuant to a written direction from any Borrower that is approved by Agent; and (ii) the proceeds of each Revolver Loan requested under Section 4.1.1(ii) or Section 4.1.3(ii) shall be disbursed by Agent by way of direct payment of the relevant interest or other Obligation. Any Loan proceeds received by any Borrower or in payment of any of the Obligations shall be deemed to have been received by all Borrowers.

               4.1.5. Telephonic Notices. Each Borrower authorizes Agent and Lenders to extend, convert or continue Loans, effect selections of Types of Loans and transfer funds to or on behalf of Borrowers based on telephonic notices or instructions from a Senior Officer or cash manager of MasTec whom Agent or any Lender in good faith believes to be acting on behalf of Borrower Agent or any Borrower. Borrowers shall confirm each such telephonic request for a Borrowing or conversion or continuation of Loans by prompt delivery to Agent of the required Notice of Borrowing or Notice of Conversion/Continuation, as applicable, duly executed by an authorized officer of Borrower Agent. If the written confirmation differs in any material respect from the action taken by Agent or Lenders, the records of Agent and Lenders shall govern. Neither Agent nor any Lender shall have any liability for any loss suffered by any Borrower as a result of Agent’s or any Lender’s acting upon its understanding of telephonic instructions or requests from a person believed in good faith by Agent or any Lender to be a person authorized by a Borrower to give such instructions or to make such requests on Borrowers’ behalf.

     4.2. Defaulting Lender. If any Lender shall, at any time, fail to make any payment to Agent or BofA that is required hereunder, Agent may, but shall not be required to, retain payments that would otherwise be made to such defaulting Lender hereunder and apply such payments to such defaulting Lender’s defaulted obligations hereunder, at such time, and in such order, as Agent may elect in its sole discretion. With respect to the payment of any funds from Agent to a Lender or from a Lender to Agent, the party failing to make the full payment when due pursuant to the terms hereof shall, upon demand by the other party, pay such amount together with interest on such amount at the Federal Funds Rate. The failure of any Lender to fund its portion of any Loan or payment in respect of an LC Obligation shall not relieve any other Lender of its obligation, if any, to fund its portion of the Revolver Loan or payment in respect of an LC Obligation on the date of Borrowing, but no Lender shall be responsible for the failure of any other Lender to make any Loan or payment in respect of an LC Obligation to be made by such Lender on the date of any Borrowing. Solely as among the Lenders and solely for purposes of voting or consenting to matters with respect to any of the Loan Documents, Collateral or any Obligations and determining a defaulting Lender’s share of payments and proceeds of Collateral pending such defaulting Lender’s cure of its defaults hereunder, a defaulting Lender shall not be deemed to be a “Lender” and such Lender’s Commitment shall be deemed to be zero (0). The

provisions of this Section 4.2 shall be solely for the benefit of Agent and Lenders and may not be enforced by Borrowers.

     4.3. Special Provisions Governing LIBOR Loans.

               4.3.1. Number of LIBOR Loans. In no event may the number of LIBOR Loans outstanding at any time to any Lender exceed 7.

               4.3.2. Minimum Amounts. Each Borrowing of LIBOR Loans pursuant to Section 4.1.1(i), and each continuation of or conversion to LIBOR Loans pursuant to Section 3.1.2 hereof, shall be in a minimum amount of $1,000,000 and integral multiples of $100,000 in excess of that amount.

               4.3.3. LIBOR Lending Office. Each Lender’s initial LIBOR Lending Office is set forth opposite its name on the signature pages hereof. Each Lender shall have the right at any time and from time to time to designate a different office of itself or of any Affiliate as such Lender’s LIBOR Lending Office, and to transfer any outstanding LIBOR Loans to such LIBOR Lending Office. No such designation or transfer shall result in any liability on the part of Borrowers for increased costs or expenses resulting solely from such designation or transfer. Increased costs for expenses resulting from a change in Applicable Law occurring subsequent to any such designation or transfer shall be deemed not to result solely from such designation or transfer.

               4.3.4. Funding of LIBOR Loans. Each Lender may, if it so elects, fulfill its obligation to make, continue or convert LIBOR Loans hereunder by causing one of its foreign branches or Affiliates (or an international banking facility created by such Lender) to make or maintain such LIBOR Loans; provided, however, that such LIBOR Loans shall nonetheless be deemed to have been made and to be held by such Lender, and the obligation of Borrowers to repay such LIBOR Loans shall nevertheless be to such Lender for the account of such foreign branch, Affiliate or international banking facility. The calculation of all amounts payable to Lender under Section 3.7 and 3.10 shall be made as if each Lender had actually funded or committed to fund its LIBOR Loan through the purchase of an underlying deposit in an amount equal to the amount of such LIBOR Loan and having a maturity comparable to the relevant Interest Period for such LIBOR Loans; provided, however, each Lender may fund its LIBOR Loans in any manner it deems fit and the foregoing presumption shall be utilized only for the calculation of amounts payable under Section 3.7 and Section 3.10.

     4.4. Borrower Agent. Each Obligor hereby irrevocably appoints MasTec and MasTec agrees to act under this Agreement, as the agent and representative of itself and each other Obligor for all purposes under this Agreement (in such capacity, “Borrower Agent”), including requesting Borrowings, selecting whether any Loan or portion thereof is to bear interest as a Base Rate Loan or a LIBOR Loan, and receiving account statements and other notices and communications to Obligors (or any of them) from Agent. Agent may rely, and shall be fully protected in relying, on any Notice of Borrowing, Notice of Conversion/Continuation, disbursement instructions, reports, information, Borrowing Base Certificate or any other notice or communication made or given by Borrower Agent, whether in its own name, on behalf of any Obligor or on behalf of “the Borrowers” or “the Obligors,” and Agent shall have no obligation to make any inquiry or request any confirmation from or on behalf of any other Borrower as to the binding effect on such Obligor of any such Notice of Borrowing, Notice of Conversion Continuation, instruction, report, information, Borrowing Base Certificate or other notice or communication, nor shall the joint and several character of Borrowers’ liability for the Obligations be affected, provided that the provisions of this Section 4.4 shall not be construed so as to preclude any Borrower from directly requesting Borrowings or taking other actions permitted to be taken by “a Borrower” hereunder. Agent may maintain a single Loan Account in the name of “MasTec” hereunder, and each Borrower expressly

agrees to such arrangement and confirms that such arrangement shall have no effect on the joint and several character of such Borrower’s liability for the Obligations.

     4.5. All Loans to Constitute One Obligation. The Loans and LC Obligations shall constitute one general obligation of Borrowers and (unless otherwise expressly provided in any Security Document) shall be secured by Agent’s Lien upon all of the Collateral; provided, however, that Agent and each Lender shall be deemed to be a creditor of each Borrower and the holder of a separate claim against each Borrower to the extent of any Obligations owed by Borrowers to Agent or such Lender.

SECTION 5. PAYMENTS

     5.1. General Payment Provisions. All payments (including all prepayments) of principal of and interest on the Loans, LC Obligations and other Obligations that are payable to Agent or any Lender shall be made to Agent in Dollars without any offset or counterclaim and free and clear of (and without deduction for) any present or future Taxes, and, with respect to payments made other than by application of balances in the Payment Account, in immediately available funds not later than 12:00 noon on the due date (and payment made after such time on the due date to be deemed to have been made on the next succeeding Business Day). All payments received by Agent shall be distributed by Agent in accordance with this Agreement, hereof, subject to the rights of offset that Agent may have as to amounts otherwise to be remitted to a particular Lender by reason of amounts due Agent from such Lender under any of the Loan Documents.

     5.2. Repayment of Revolver Loans.

               5.2.1. Payment of Principal . The outstanding principal amounts with respect to the Revolver Loans shall be repaid as follows:

          (i) Any portion of the Revolver Loans consisting of the principal amount of Base Rate Loans shall be paid by Borrowers to Agent, for the Pro Rata benefit of Lenders (or, in the case of Swingline Loans, for the sole benefit of BofA) unless timely converted to a LIBOR Loan in accordance with this Agreement, immediately upon (a) each receipt by Agent, any Lender or Borrowers of any proceeds of any of the Accounts or other Collateral, to the extent of such proceeds, (b) the Commitment Termination Date, and (c) in the case of Swingline Loans, the earlier of BofA’s demand for payment or on each Settlement Date with respect to all Swingline Loans outstanding on such date.

          (ii) Any portion of the Revolver Loans consisting of the principal amount of LIBOR Loans shall be paid by Borrowers to Agent, for the Pro Rata benefit of Lenders, unless converted to a Base Rate Loan or continued as a LIBOR Loan in accordance with the terms of this Agreement, immediately upon (a) the last day of the Interest Period applicable thereto and (b) the Commitment Termination Date. In no event shall Borrowers be authorized to make a voluntary prepayment with respect to any Revolver Loan outstanding as a LIBOR Loan prior to the last day of the Interest Period applicable thereto unless (x) otherwise agreed in writing by Agent or Borrowers are otherwise expressly authorized or required by any other provision of this Agreement to pay any LIBOR Loan outstanding on a date other than the last day of the Interest Period applicable thereto, and (y) Borrowers pay to Agent, for the Pro Rata benefit of Lenders, concurrently with any prepayment of a LIBOR Loan, any amount due Agent and Lenders under Section 3.10 hereof as a consequence of such prepayment. Notwithstanding the foregoing provisions of this Section 5.2.1(ii), if, on any date that Agent receives proceeds of any of the Accounts or other Collateral, there are no Revolver Loans outstanding as Base Rate Loans, Agent may either hold such proceeds as cash security for the timely payment of the

Obligations or apply such proceeds to any outstanding Revolver Loans bearing interest as LIBOR Loans as the same become due and payable (whether at the end of the applicable Interest Periods or on the Commitment Termination Date).

          (iii) Notwithstanding anything to the contrary contained elsewhere in this Agreement, if an Out-of-Formula Condition shall exist, Borrowers shall, on the sooner to occur of Agent’s demand or the first Business Day after any Borrower has obtained knowledge of such Out-of-Formula Condition, repay the outstanding Revolver Loans that are Base Rate Loans in an amount sufficient to reduce the aggregate unpaid principal amount of all Revolver Loans by an amount equal to such excess; and, if such payment of Base Rate Loans is not sufficient to eliminate the Out-of-Formula Condition, then Borrowers shall immediately deposit with Agent, for the Pro Rata benefit of Lenders, for application to any outstanding Revolver Loans bearing interest as LIBOR Loans as the same become due and payable (whether at the end of the applicable Interest Periods or on the Commitment Termination Date) cash in an amount sufficient to eliminate such Out-of-Formula Condition, and Agent may (a) hold such deposit as cash security pending disbursement of same to Lenders for application to the Obligations, or (b) if a Default or Event of Default exists, immediately apply such proceeds to the payment of the Obligations, including the Revolver Loans outstanding as LIBOR Loans (in which event Borrowers shall also pay to Agent for the Pro Rata benefit of Lenders any amounts required by Section 3.10 to be paid by reason of the prepayment of a LIBOR Loan prior to the last day of the Interest Period applicable thereto).

               5.2.2. Payment of Interest. Interest accrued on the Revolver Loans shall be due and payable on (i) the first day of each month (for the immediately preceding month), computed through the last day of the preceding month, with respect to any Revolver Loan (whether a Base Rate Loan or LIBOR Loan) and (ii) the last day of the applicable Interest Period in the case of a LIBOR Loan. Accrued interest shall also be paid by Borrowers on the Commitment Termination Date. With respect to any Base Rate Loan converted into a LIBOR Loan pursuant to Section 3.1.2 on a day when interest would not otherwise have been payable with respect to such Base Rate Loan, accrued interest to the date of such conversion on the amount of such Base Rate Loan so converted shall be paid on the conversion date.

               5.2.3. Mandatory Prepayments. Borrowers shall pay the entire unpaid principal balance of the Loans, and all accrued but unpaid interest thereon, upon the Commitment Termination Date. Borrowers shall also prepay the Loans as follows:

          (i) Borrowers shall prepay the Loans in the amount of Net Disposition Proceeds from Permitted Asset Dispositions provided that Net Disposition Proceeds received from a Canadian Obligor shall be held by Agent as security for the payment of the Canadian Obligor Guarantee of such Canadian Obligor;

          (ii) Borrowers shall prepay the Loans from the proceeds of insurance or condemnation awards paid in respect of any Equipment or Real Estate unless and to the extent Borrowers are authorized to use such proceeds pursuant to Section 8.1.2(ii); and

          (iii) Borrowers shall prepay the Loans from the net proceeds received by any Borrower from any issuance of any Debt or Equity Interests in an amount sufficient to cause Availability at the time of such issuance of Debt or Equity Interests, and immediately after giving effect thereto, to equal or exceed $50,000,000.

               5.2.4. Application of Prepayments. All distributions of prepayments by Agent to Lenders shall be on a Pro Rata basis. Each Lender shall apply the portion of a prepayment that is to be applied to principal installments first to outstanding Base Rate Loans and then to any outstanding LIBOR Loans with the shortest Interest Periods remaining; but if application to any LIBOR Loans would cause the same to be paid prior to the end of an applicable Interest Period, then, by prior written notice to Agent, Borrowers may elect as to such LIBOR Loan to deliver cash to Agent in the amount of the required prepayment, to be held by Agent as cash collateral until the end of the applicable Interest Period, at which time Agent shall disburse such cash collateral to the affected Lenders for application to such LIBOR Loans.

     5.3. Reserved.

     5.4. Payment of Other Obligations. The balance of the Obligations requiring the payment of money, including the LC Obligations and Extraordinary Expenses incurred by Agent or any Lender, shall be repaid by Borrowers to Agent for allocation among Agent and Lenders as provided in the Loan Documents, or, if no date of payment is otherwise specified in the Loan Documents, on demand.

     5.5. Marshaling; Payments Set Aside. None of Agent or Lenders shall be under any obligation to marshal any assets in favor of Borrowers or any other Obligor or against or in payment of any or all of the Obligations. To the extent that Borrowers make a payment to Agent or Lenders or Agent or any Lender receives payment from the proceeds of any Collateral or exercises its right of setoff, and such payment or the proceeds of such Collateral or setoff (or any part thereof) are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, receiver or any other Person, then to the extent of any loss by Agent or Lenders, the Obligations or part thereof originally intended to be satisfied, and all Liens, rights and remedies therefor, shall be revived and continued in full force and effect as if such payment or proceeds had not been made or received and any such enforcement or setoff had not occurred. The provisions of the immediately preceding sentence of this Section 5.5 shall survive any termination of the Commitments and Full Payment of the Obligations.

     5.6. Post Default Allocation of Payments.

               5.6.1. Allocation. For so long as an Event of Default exists, all monies to be applied to the Obligations, whether such monies represent voluntary or mandatory payments or prepayments by one or more Obligors or are received pursuant to demand for payment or realized from any disposition of Collateral and irrespective of any designation by Borrowers of the Obligations intended to be satisfied, shall be allocated among Agent and such of the Lenders as are entitled thereto (and, with respect to monies allocated to Lenders, on a Pro Rata basis unless otherwise provided herein): (i) first, to Agent to pay principal and accrued interest on any portion of the Revolver Loans (including Protective Advances) which Agent may have advanced on behalf of any Lender and for which Agent has not been reimbursed by such Lender or Borrowers, until Full Payment of all such Obligations; (ii) second, to BofA to pay the principal and accrued interest on any portion of the Swingline Loans outstanding, to be shared with Lenders that have acquired and paid for a participating interest in such Swingline Loans, until Full Payment of all such Obligations; (iii) third, to the extent that Issuing Bank has not received from any Participating Lender a payment as required by Section 2.3.2 hereof, to Issuing Bank to pay all such required payments from each Participating Lender, until Full Payment of all such Obligations; (iv) fourth, to Agent to pay the amount of Extraordinary Expenses (including Protective Advances) that have not been reimbursed to Agent by Borrowers or Lenders, together with interest accrued thereon at the rate applicable to Revolver Loans that are Base Rate Loans, until Full Payment of all such Obligations; (v) fifth, to Agent to pay any Indemnified Amount that has not been paid pursuant to any indemnity of Agent Indemnitees by any Obligor or to pay amounts owing by Lenders to Agent Indemnities pursuant to Section 13.6, in each case, together with interest accrued thereon at the rate applicable to Revolver Loans

that are Base Rate Loans, until Full Payment of all such Obligations; (vi) sixth, to Agent to pay any fees due and payable to Agent, until Full Payment of all such Obligations; (vii) seventh, to each Lender, ratably, for any Indemnified Amount that such Lender has paid to Agent Indemnitees pursuant to its indemnity of Agent Indemnitees and any Extraordinary Expenses that such Lender has reimbursed to Agent or such Lender has incurred, to the extent that such Lender has not been reimbursed by Obligors therefor; (viii) eighth, to Issuing Bank to pay principal and interest with respect to LC Obligations (or to the extent any of the LC Obligations are contingent and an Event of Default then exists, deposited in the Cash Collateral Account to Cash Collateralize the LC Obligations), which payment shall be shared with the Participating Lenders in accordance with Section 2.3.2(iii) hereof; (ix) ninth, to Lenders in payment of the unpaid principal and accrued interest in respect of the Loans and other Obligations (excluding Banking Relationship Debt) then outstanding, in such order of application as shall be designated by Agent (acting at the direction or with the consent of the Required Lenders); and (x) tenth, to Lenders and any Affiliates of Lenders, ratably, in payment of any Banking Relationship Debt owed to such Persons and secured by the Collateral hereunder. For the avoidance of doubt, to the extent constituting an Indemnified Amount, any indemnity, guarantee or other payment made by Agent or any Lender as described in Section 3.4.2 with respect to Banking Relationship Debt shall be allocated to tenth priority, above. The allocations set forth in this Section 5.6 are solely to determine the rights and priorities of Agent and Lenders as among themselves and may be changed by Agent and Lenders without notice to or the consent or approval of any Borrower or any other Person.

               5.6.2. Erroneous Allocation. Agent shall not be liable for any allocation or distribution of payments made by it in good faith and, if any such allocation or distribution is subsequently determined to have been made in error, the sole recourse of any Lender to which payment was due but not made shall be to recover from the other Lenders any payment in excess of the amount to which such other Lenders are determined to be entitled (and such other Lenders hereby agree to return to such Lender any such erroneous payments received by them).

     5.7. Application of Payments and Collateral Proceeds. All Payment Items received by Agent by 12:00 noon, on any Business Day shall be deemed received on that Business Day. All Payment Items received by Agent after 12:00 noon, on any Business Day shall be deemed received on the following Business Day. Each Borrower irrevocably waives the right to direct the application of any and all payments and Collateral proceeds at any time or times hereafter received by Agent or any Lender from or on behalf of Borrowers, and each Borrower does hereby irrevocably agree that Agent shall have the continuing exclusive right to apply and reapply any and all such payments and Collateral proceeds received at any time or times hereafter by Agent or its agent against the Obligations, in such manner as Agent may deem advisable, notwithstanding any entry by Agent upon any of its books and records; provided, however, that any payments or proceeds of Collateral received by Agent on any date that an Event of Default does not exist shall be applied in accordance with any provisions of this Agreement that govern the application of such payment or proceeds. If, as the result of Agent’s collection of proceeds of Accounts and other Collateral as authorized by Section 8.2.6 a credit balance exists, such credit balance shall not accrue interest in favor of Borrowers, but shall be available to Borrowers at any time or times for so long as no Default or Event of Default exists. Agent may apply such credit balance against any of the Obligations upon and after the occurrence of an Event of Default in the manner specified in Section 5.6.1.

     5.8. Loan Accounts; the Register; Account Stated.

               5.8.1. Loan Accounts. Each Lender shall maintain in accordance with its usual and customary practices an account or accounts (a “Loan Account”) evidencing the Debt of Borrowers to such Lender resulting from each Loan owing to such Lender from time to time, including the amount of principal and interest payable to such Lender from time to time hereunder and under each Note payable to such Lender. Any failure of a Lender to record in the Loan Account, or any error in doing so, shall not

limit or otherwise affect the obligation of Borrowers hereunder (or under any Note) to pay any amount owing hereunder to such Lender.

               5.8.2. The Register. Agent shall maintain a register (the “Register”), which shall include a master account and a subsidiary account for each Lender and in which accounts (taken together) shall be recorded (i) the date and amount of each Borrowing made hereunder, the Type of each Loan comprising such Borrowing and any Interest Period applicable thereto, (ii) the effective date and amount of each Assignment and Acceptance delivered to and accepted by it and the parties thereto, (iii) the amount of any principal or interest due and payable or to become due and payable from Borrowers to each Lender hereunder or under the Notes, and (iv) the amount of any sum received by Agent from Borrowers or any other Obligor and each Lender’s Pro Rata share thereof. The Register shall be available for inspection by Borrowers or any Lender at the offices of Agent at any reasonable time and from time to time upon reasonable prior notice. Any failure of Agent to record in the Register, or any error in doing so, shall not limit or otherwise affect the obligation of Borrowers hereunder (or under any Note) to pay any amount owing with respect to the Loans or provide the basis for any claim against Agent.

               5.8.3. Entries Binding. The entries made in the Register and each Loan Account shall constitute rebuttably presumptive evidence of the information contained therein; provided, however, that if a copy of information contained in the Register or any Loan Account is provided to any Person, or any Person inspects the Register or any Loan Account, at any time or from time to time, then the information contained in the Register or the Loan Account, as applicable, shall be conclusive and binding on such Person for all purposes absent manifest error, unless such Person notifies Agent in writing within 30 days after such Person’s receipt of such copy or such Person’s inspection of the Register or Loan Account of its intention to dispute the information contained therein.

     5.9. Gross Up for Taxes. If Obligors shall be required by Applicable Law to withhold or deduct any Taxes from or in respect of any sum payable under this Agreement or any of the other Loan Documents or Agent or any Lender shall be liable to remit any such Taxes otherwise payable by Obligors, in either case, (a) the sum payable to Agent or such Lender shall be increased as may be necessary so that, after making all required withholding, remittances or deductions, Agent or such Lender (as the case may be) receives an amount equal to the sum it would have received had no such withholding, remittances or deductions been made, (b) Obligors shall make such withholding or deductions, and (c) Obligors shall pay the full amount withheld or deducted to the relevant taxation authority or other authority in accordance with Applicable Law.

     5.10. Withholding Tax Exemption. At least 5 Business Days prior to the first date on which interest or fees are payable hereunder for the account of any Foreign Lender, such Foreign Lender agrees that it will deliver to Borrowers and Agent 2 duly completed copies of United States Internal Revenue Service Form W-8BEN or W-8ECI (or any subsequent replacement substitute or form therefor), certifying in either case that such Lender is entitled to receive payment under this Agreement and its Note without deduction or withholding of any United States federal income taxes. Each Foreign Lender which so delivers a Form W-8BEN or W-8ECI further undertakes to deliver to Borrowers and Agent 2 additional copies of such form (or a successor form) on or before the date that such form expires (currently, 3 successive calendar years for Form W-8BEN and one calendar year for Form W-8ECI) or becomes obsolete or after the occurrence of any event requiring a change in the most form so delivered by it, and such amendments thereto or extensions or renewals thereof as may be reasonably requested by Borrowers or Agent, in each case, certifying that such Foreign Lender is entitled to receive payments under this Agreement and its Notes without deduction or withholding of any United States federal income taxes, unless an event (including any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required that renders all such forms inapplicable or that would prevent such Foreign Lender from duly completing and delivering any such form with respect to it

and such Lender advises Borrowers and Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income taxes.

     5.11. Nature and Extent of Each Borrower’s Liability.

               5.11.1. Joint and Several Liability. Each Borrower shall be liable for, on a joint and several basis, and hereby guarantees the timely payment by all other Borrowers of, all of the Loans and other Obligations, regardless of which Borrower actually may have received the proceeds of any Loans or other extensions of credit hereunder or the amount of such Loans received or the manner in which Agent or any Lender accounts for such Loans or other extensions of credit on its books and records, it being acknowledged and agreed that Loans to any Borrower inure to the mutual benefit of all Borrowers and that Agent and Lenders are relying on the joint and several liability of Borrowers in extending the Loans and other financial accommodations hereunder. Each Borrower hereby unconditionally and irrevocably agrees that upon default in the payment when due (whether at stated maturity, by acceleration or otherwise) of any principal of, or interest owed on, any of the Loans or other Obligations, such Borrower shall forthwith pay the same, without notice or demand.

               5.11.2. Unconditional Nature of Liability. Each Borrower’s joint and several liability hereunder with respect to, and guaranty of, the Loans and other Obligations shall, to the fullest extent permitted by Applicable Law, be unconditional irrespective of (i) the validity, enforceability, avoidance or subordination of any of the Obligations or of any promissory note or other document evidencing all or any part of the Obligations, (ii) the absence of any attempt to collect any of the Obligations from any other Obligor or any Collateral or other security therefor, or the absence of any other action to enforce the same, (iii) the waiver, consent, extension, forbearance or granting of any indulgence by Agent or any Lender with respect to any provision of any instrument evidencing or securing the payment of any of the Obligations, or any other agreement now or hereafter executed by any other Borrower and delivered to Agent or any Lender, (iv) the failure by Agent to take any steps to perfect or maintain the perfected status of its security interest in or Lien upon, or to preserve its rights to, any of the Collateral or other security for the payment or performance of any of the Obligations or Agent’s release of any Collateral or of its Liens upon any Collateral, (v) Agent’s or Lenders’ election, in any proceeding instituted under the Bankruptcy Code, for the application of Section 1111(b)(2) of the Bankruptcy Code or under the Bankruptcy and Insolvency Act (Canada) or the Companies Creditors Arrangement Act (Canada), (vi) any borrowing or grant of a security interest by any other Borrower, as debtor-in-possession under Section 364 of the Bankruptcy Code, (vii) the release or compromise, in whole or in part, of the liability of any Obligor for the payment of any of the Obligations, (viii) any amendment or modification of any of the Loan Documents or any waiver of a Default or Event of Default, (ix) any increase in the amount of the Obligations beyond any limits imposed herein or in the amount of any interest, fees or other charges payable in connection therewith, or any decrease in the same, (x) the disallowance of all or any portion of Agent’s or any Lender’s claims against any other Obligor for the repayment of any of the Obligations under Section 502 of the Bankruptcy Code or under the Bankruptcy and Insolvency Act (Canada) or the Companies Creditors Arrangement Act (Canada), or (xi) any other circumstance that might constitute a legal or equitable discharge or defense of any Borrower. After the occurrence and during the continuance of any Event of Default, Agent may proceed directly and at once, without notice to any Obligor, against any or all of Obligors to collect and recover all or any part of the Obligations, without first proceeding against any other Obligor or against any Collateral or other security for the payment or performance of any of the Obligations, and each Borrower waives any provision under Applicable Law that might otherwise require Agent to pursue or exhaust its remedies against any Collateral or Obligor before pursuing another Obligor. Each Borrower consents and agrees that Agent shall be under no obligation to marshal any assets in favor of any Obligor or against or in payment of any or all of the Obligations.

               5.11.3. No Reduction in Liability for Obligations. No payment or payments made by an Obligor or received or collected by Agent from a Borrower or any other Person by virtue of any action or proceeding or any setoff or appropriation or application at any time or from time to time in reduction of or in payment of the Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of any Borrower under this Agreement, each of whom shall remain liable for the payment and performance of all Loans and other Obligations until the Full Payment of the Obligations.

               5.11.4. Contribution. Each Borrower is unconditionally obligated to repay the Obligations as a joint and several obligor under this Agreement. If, as of any date, the aggregate amount of payments made by a Borrower on account of the Obligations and proceeds of such Borrower’s Collateral that are applied to the Obligations exceeds the aggregate amount of Loan proceeds actually used by such Borrower in its business (such excess amount being referred to as an “Accommodation Payment”), then each of the other Borrowers (each such Borrower being referred to as a “Contributing Borrower”) shall be obligated to make contribution to such Borrower (the “Paying Borrower”) in an amount equal to (A) the product derived by multiplying the sum of each Accommodation Payment of each Borrower by the Allocable Percentage (as defined below) of the Borrower from whom contribution is sought less (B) the amount, if any, of the then outstanding Accommodation Payment of such Contributing Borrower (such last mentioned amount which is to be subtracted from the aforesaid product to be increased by any amounts theretofore paid by such Contributing Borrower by way of contribution hereunder, and to be decreased by any amounts theretofore received by such Contributing Borrower by way of contribution hereunder); provided, however, that a Paying Borrower’s recovery of contribution hereunder from the other Borrowers shall be limited to that amount paid by the Paying Borrower in excess of its Allocable Percentage of all Accommodation Payments then outstanding of all Borrowers. As used herein, the term “Allocable Percentage” shall mean, on any date of determination thereof, a fraction the denominator of which shall be equal to the number of Borrowers who are parties to this Agreement on such date and the numerator of which shall be 1; provided, however, that such percentages shall be modified in the event that contribution from a Borrower is not possible by reason of insolvency, bankruptcy or otherwise by reducing such Borrower’s Allocable Percentage equitably and by adjusting the Allocable Percentage of the other Borrowers proportionately so that the Allocable Percentages of all Borrowers at all times equals 100%.

               5.11.5. Subordination. Each Borrower hereby subordinates any claims, including any right of payment, subrogation, contribution and indemnity, that it may have from or against any other Obligor, and any successor or assign of any other Obligor, including any trustee, receiver or debtor-in-possession, howsoever arising, due or owing or whether heretofore, now or hereafter existing, to the Full Payment of all of the Obligations.

SECTION 6. TERM AND TERMINATION OF COMMITMENTS

     6.1. Term of Commitments. Subject to each Lender’s right to cease making Loans and other extensions of credit to Borrowers when any Default or Event of Default exists or upon termination of the Commitments as provided in Section 6.2 hereof, the Commitments shall be in effect from the date hereof through the close of business on May 10, 2013 (the “Term”) unless sooner terminated as provided in Section 6.2.

     6.2. Termination.

               6.2.1. Termination by Agent. Agent may (and upon the direction of the Required Lenders, shall) terminate the Commitments without notice at any time that an Event of Default exists; provided, however, that the Commitments shall automatically terminate as provided in Section 12.2 hereof.

               6.2.2. Termination by Borrowers. Upon at least 90 days prior written notice to Agent, Borrowers may, at their option, terminate the Commitments; provided, however, no such termination by Borrowers shall be effective until Full Payment of the Obligations. Any notice of termination given by Borrowers shall be irrevocable unless Agent otherwise agrees in writing. Borrowers may elect to terminate the Commitments in their entirety only provided that nothing contained herein shall affect Borrowers’ right to voluntarily reduce the Revolver Commitments as provided in Section 2.2. No section of this Agreement, Type of Loan available hereunder or Commitment may be terminated by Borrowers singly.

               6.2.3. Reserved

               6.2.4. Effect of Termination. On the effective date of termination of the Commitments by Agent or by Borrowers, all of the Obligations shall be immediately due and payable, Lenders shall have no obligation to make any Loans and Issuing Bank shall have no obligation to issue any Letters of Credit, and Lenders may terminate any Bank Products (including any services or products under Cash Management Agreements). All undertakings, agreements, covenants, warranties and representations of Borrowers contained in the Loan Documents shall survive any such termination and Agent shall retain its Liens in the Collateral and all of its rights and remedies under the Loan Documents notwithstanding such termination until Full Payment of the Obligations. Notwithstanding the Full Payment of the Obligations, Agent shall not be required to terminate its Liens in any of the Collateral unless, with respect to any loss or damage Agent may incur as a result of the dishonor or return of any Payment Items applied to the Obligations, Agent shall have received either (i) a written agreement, executed by Borrowers and any Person deemed financially responsible by Agent whose loans or other advances to Borrowers are used in whole or in part to satisfy the Obligations, indemnifying Agent and Lenders from any such loss or damage; or (ii) such monetary reserves and Liens on the Collateral for such period of time as Agent, in its reasonable discretion, may deem necessary to protect Agent from any such loss or damage. The provisions of Sections 3.4, 3.7, 3.8, 3.10, 5.5, 5.9 and this Section 6.2.4 and all obligations of Borrowers to indemnify Agent or any Lender pursuant to this Agreement or any of the other Loan Documents, shall in all events survive any termination of the Commitments and Full Payment of the Obligations.

SECTION 7. COLLATERAL

     7.1. Grant of Security Interest . To secure the prompt payment and performance of all of the Obligations, each Obligor hereby (i) confirms the mortgage, pledge and assignment to Agent, for the benefit of the Secured Parties of the Collateral under (and as defined in) the Existing Loan Agreement and the other Loan Documents (as defined in the Existing Loan Agreement), and the creation in favor of Agent, for the benefit of the Secured Parties, under the Existing Loan Agreement and such other Loan Documents of a continuing Lien in such Collateral, all as security for the Obligations, and (ii) grants to Agent, for the benefit of Secured Parties, a continuing security interest in and Lien upon the following Property and interests in Property of such Obligor, whether now owned or existing or hereafter created, acquired or arising and wheresoever located:

          (xii) all accessions to, substitutions for and all replacements, products and cash and non-cash proceeds of (i) through (xi) above, including proceeds of and unearned premiums with respect to insurance policies insuring any of the Collateral and claims against any Person for loss of, damage to or destruction of any of the Collateral; and

          (xiii) all books and records (including customer lists, files, correspondence, tapes, computer programs, print-outs, and other computer materials and records) of such Borrower pertaining to any of (i) through (xii) above.

     Notwithstanding anything to the contrary set forth herein, Agent shall not be deemed to have been granted a security interest in, and the term “Collateral” shall not include, any Equity Interests owned or held by any Borrower in DirectStar.

     7.2. Lien on Deposit Accounts. As additional security for the payment and performance of the Obligations, each Borrower hereby grants to Agent, for the benefit of Secured Parties, a continuing security interest in and Lien upon all of such Borrower’s right, title and interest in and to each Deposit Account of such Borrower (other than the Insurance Cash Collateral Account) and in and to any deposits or other sums at any time credited to each such Deposit Account, including any sums in any blocked account or any special lockbox account and in the accounts in which sums are deposited. In connection with the foregoing, each Borrower hereby authorizes and directs each such bank or other depository to pay or deliver to Agent upon its written demand therefor made at any time that an Event of Default exists and without further notice to such Borrower (such notice being hereby expressly waived), all balances in each such Deposit Account maintained by such Borrower with such depository for application to the Obligations then outstanding, and the rights given Agent in this Section shall be cumulative with and in addition to Agent’s other rights and remedies in regard to the foregoing Property as proceeds of Collateral. Each Borrower hereby irrevocably appoints Agent as such Borrower’s attorney-in-fact to collect any and all such balances to the extent any such payment is not made to Agent by such bank or other depository after demand thereon is made by Agent pursuant hereto.

     7.3. Real Estate Collateral.

               7.3.1. Lien on Real Estate. The due and punctual payment and performance of the Obligations shall also be secured by the Lien created by the Mortgages upon all Real Estate of each Borrower described therein. The Mortgages shall be executed by Borrowers in favor of Agent (for the benefit of Secured Parties) as provided in this Agreement and shall be duly recorded, at Borrowers’ expense, in each office where such recording is required to constitute a fully perfected Lien upon the Real Estate covered thereby. Promptly after any Borrower’s obtaining any interest in any Real Estate, Borrowers shall execute and deliver to Agent, for the benefit of Secured Parties, a Mortgage sufficient to convey and perfect, upon recordation thereof in the proper real estate records, in favor of Agent a first priority Lien upon such interest as security for the payment or performance of the Obligations.

               7.3.2. Collateral Assignment of Leases. To further secure to the prompt payment and performance of the Obligations, each Borrower hereby grants, transfers and assigns to Agent, for the benefit of Secured Parties, and hereby grants to Agent, for the benefit of Secured Parties, a security interest in and Lien upon all of such Borrower’s right, title and interest in, to and under all now or hereafter existing leases of real Property to which such Borrower is a party, whether as lessor or lessee, and all extensions, renewals and modifications thereof.

     7.4. Other Collateral.

               7.4.1. Cash Collateral. In addition to the items of Property referred to in Section 7.1 above, (i) the Obligations shall also be secured by the Cash Collateral (other than any Cash Collateral held in the LC Collateral Account) and all of the other items of Property from time to time described in any of the Security Documents as security for any of the Obligations, including all of the Collateral described in the Canadian Security Agreement, in each case to the extent provided herein and (ii) the LC Obligations relating to the Ace LC, and only such LC Obligation, shall be secured by all cash, Cash Equivalents and other Property from time to time in the LC Collateral Account.

               7.4.2. Commercial Tort Claims. Obligors shall promptly notify Agent in writing upon any Obligor’s obtaining a Commercial Tort Claim (other than, for so long as no Default or Event of Default exists, a Commercial Tort Claim that is less than $100,000) after the Closing Date against any Person and, upon Agent’s written request, promptly execute such instruments or agreements and do such other acts or things deemed appropriate by Agent to confer upon Agent (for the benefit of Secured Parties) a security interest in each such Commercial Tort Claim.

               7.4.3. Certain After-Acquired Collateral. Obligors shall promptly notify Agent in writing upon any Obligor’s obtaining any Collateral after the Closing Date consisting of Deposit Accounts, Investment Property, Letter-of-Credit Rights, Chattel Paper or Intellectual Property consisting of registered trademarks or patents, and, upon Agent’s request, shall promptly execute such documents and do such other acts or things deemed appropriate by Agent to confer upon Agent a duly perfected, first priority Lien upon, and (to the extent applicable for perfection of a Lien) control with respect to such Collateral; promptly notify Agent in writing upon any Borrower’s obtaining any Collateral after the Closing Date consisting of Documents or Instruments and, upon Agent’s request, shall promptly execute such documents and do such other acts or things deemed appropriate by Agent to deliver to Agent possession of such Documents as are negotiable and such Instruments, and, with respect to non-negotiable Documents, to have such non-negotiable Documents issued in the name of Agent; and with respect to Collateral in the possession of a third party, other than certificated securities and Goods covered by a Document, such Borrower shall obtain an acknowledgment from the third party that is in possession of such Collateral that such third party holds the Collateral for the benefit of Agent.

     7.5. No Assumption of Liability. The security interest granted pursuant to this Agreement is granted as security only and shall not subject Agent or any Lender to, or in any way alter or modify, any obligation or liability of Borrowers with respect to or arising out of the Collateral.

     7.6. Lien Perfection; Further Assurances. Promptly after Agent’s request therefor, Obligors shall execute or cause to be executed and deliver to Agent such instruments, assignments, title certificates or other documents as are necessary under the UCC, the PPSA or other Applicable Law (including any motor vehicle certificates of title act) to perfect (or continue the perfection of) Agent’s Lien upon the Collateral and shall take such other action as may be requested by Agent to give effect to or carry out the intent and purposes of this Agreement. Unless prohibited by Applicable Law, each Obligor hereby irrevocably authorizes Agent to execute and file in any jurisdiction any financing statement or amendment thereto on such Obligor’s behalf, including financing statements that indicate the Collateral (i) as all assets or all personal property of such Obligor or words to similar effect or (ii) as being of equal or lesser scope, or with greater or lesser detail, than as set forth in this Section 7. Each Obligor also hereby ratifies its authorization for Agent to have filed in any jurisdiction any like financing statement (or equivalent document in any applicable jurisdiction) or amendment thereto if filed prior to the date hereof. The parties agree that, to the extent permitted by Applicable Law, a carbon, photographic or other reproduction of this Agreement shall be sufficient as a financing statement and may be filed in any appropriate office in lieu thereof.

     7.7. Foreign Subsidiary Stock. Notwithstanding anything to the contrary set forth in Section 7.1 above, the types or items of Collateral described in such Section shall include only sixty-six percent (66%) of the Equity Interests of any Foreign Subsidiary, and shall not include the Equity Interests in any Foreign Subsidiary in existence on the date of this Agreement that is organized under the laws of any jurisdiction other than Canada or a province of Canada and that is listed on Schedule 7.7 hereto.

SECTION 8. COLLATERAL ADMINISTRATION

     8.1. General Provisions.

               8.1.1. Location of Collateral . All tangible items of Collateral, other than Inventory in transit, shall at all times be kept by Obligors at one or more of the business locations of Obligors set forth in Schedule 8.1.1 hereto and shall not be moved therefrom, except that in the absence of an Event of Default and acceleration of the maturity of the Obligations in consequence thereof, Obligors may (i) make sales or other dispositions of any Collateral to the extent authorized by Section 10.2.10 hereof and (ii) move Inventory or Equipment or any record relating to any Collateral to a

location in the United States or Canada other than those shown on Schedule 8.1.1 hereto so long as (a) Obligors have given Agent written notice of each such new location by the last day of the Fiscal Quarter in which any Inventory or Equipment were moved to such location, (b) prior to moving any Inventory or Equipment to such location there have been filed any UCC or PPSA financing statements and any other appropriate documentation necessary to perfect or continue the perfection of Agent’s first priority Liens with respect to such Inventory or Equipment, and (c) the aggregate fair market value or book value, whichever is more, of the Inventory and Equipment moved to Canada from the United States after the date of this Agreement does not exceed $1,000,000. Notwithstanding anything to the contrary contained in this Agreement, no Obligor shall be permitted to keep, store or otherwise maintain any Collateral at any location (including any location described in Section 8.1.1), unless (i) an Obligor is the owner of such location, (ii) an Obligor leases such location and the landlord has executed in favor of Agent a Lien Waiver, or (iii) the Collateral consists of Inventory placed with a warehouseman, bailee or processor, Agent has received from such warehouseman, bailee or processor an acceptable Lien Waiver and an appropriate UCC or PPSA financing statement has been filed with the appropriate Governmental Authority in the jurisdiction where such warehouseman, bailee or processor is located in order to perfect, or to maintain the uninterrupted perfection of, Agent’s security interest in such Inventory.

               8.1.2. Insurance of Collateral; Condemnation Proceeds.

               (i) Each Obligor shall maintain and pay for insurance upon all Collateral, wherever located, covering casualty, hazard, public liability, theft, malicious mischief, and such other risks in such amounts and with such insurance companies as are reasonably satisfactory to Agent. Schedule 8.1.2 describes all insurance of Obligors in effect on the date hereof. All proceeds payable under each such policy shall be payable to Agent for application to the Obligations. Obligors shall deliver the certified copies of such policies to Agent with satisfactory lender’s loss payable endorsements reasonably satisfactory to Agent naming Agent as sole loss payee, assignee or additional insured, as appropriate. Each policy of insurance or endorsement shall contain a clause requiring the insurer to give not less than 30 days prior written notice to Agent in the event of cancellation of the policy for any reason whatsoever and a clause specifying that the interest of Agent shall not be impaired or invalidated by any act or neglect of any Obligor or the owner of the Property or by the occupation of the premises for purposes more hazardous than are permitted by said policy. If any Obligor fails to provide and pay for such insurance, Agent may, at its option, but shall not be required to, procure the same and charge Obligors therefor. Each Obligor agrees to deliver to Agent, promptly as rendered, true copies of all reports made in any reporting forms to insurance companies. For so long as no Event of Default exists, each Obligor shall have the right to settle, adjust and compromise any claim with respect to any insurance maintained by such Obligor provided that all proceeds thereof are applied in the manner specified in this Agreement, and Agent shall promptly provide any necessary endorsement to any checks or drafts issued in payment of any such claim. At any time that an Event of Default exists, only Agent shall be authorized to settle, adjust and compromise such claims, Agent shall have all rights and remedies with respect to such policies of insurance as are provided for in this Agreement and the other Loan Documents.

               (ii) Any proceeds of insurance referred to in this Section 8.1.2 and any condemnation awards that are paid to Agent in connection with a condemnation of any of the Collateral shall be paid to Agent and applied to any Obligations outstanding as Agent shall determine (or, with respect to insurance proceeds paid to Agent in connection with Collateral of a Canadian Obligor, held by Agent as security for the payment of the Canadian Obligor Guarantee of such Canadian Obligor); provided, however, that if an Event of Default exists on the date of Agent’s receipt thereof, Agent shall apply such proceeds (other than insurance proceeds with respect to Collateral of a Canadian Obligor) to the Obligations in the order of application

provided in Section 5.6.1 (or, in the case of insurance proceeds with respect to Collateral of a Canadian Obligor Agent shall hold such proceeds as security for the payment of the Canadian Obligor Guarantee of such Canadian Obligor). Notwithstanding the foregoing, if requested by Borrowers in writing within 5 days after Agent’s receipt of insurance proceeds relating to any loss or destruction of Equipment or Real Estate (during which 5-day period, Agent shall hold such proceeds as security for, but without application to, the Obligations unless a Default or Event of Default exists) and if no Material Adverse Effect could reasonably be expected to result from any insured loss with respect to such Collateral, Agent shall allow Borrowers to use proceeds of insurance to repair or replace any damaged or destroyed Equipment or Real Estate so long as (1) no Default or Event of Default exists, (2) such repair or replacement is promptly undertaken and concluded, (3) replacements of buildings are constructed on the sites of the original casualties and are of comparable size, and quality and utility to the destroyed buildings, (4) the repaired or replaced Property is at all times free and clear of Liens other than Permitted Liens that are not Purchase Money Liens, (5) Borrowers comply with such disbursement procedures for such proceeds as Agent may reasonably impose for repair or replacement, and (6) the amount of proceeds from any single casualty affecting Equipment or Real Estate does not exceed $1,000,000.

               8.1.3. Protection of Collateral. All expenses of protecting, storing, warehousing, insuring, handling, maintaining and shipping any Collateral, all Taxes imposed under any Applicable Law on any of the Collateral or in respect of the sale thereof, and all other payments required to be made by Agent to any Person to realize upon any Collateral shall be borne and paid by Obligors. Agent shall not be liable or responsible in any way for the safekeeping of any of the Collateral or for any loss or damage thereto (except for reasonable care in the custody thereof while any Collateral is in Agent’s actual possession) or for any diminution in the value thereof, or for any act or default of any warehouseman, carrier, forwarding agency, or other Person whomsoever, but the same shall be at Borrowers’ sole risk.

               8.1.4. Defense of Title to Collateral. Each Obligor shall at all times defend such Obligor’s title to the Collateral and Agent’s Liens therein against all Persons and all claims and demands whatsoever other than Permitted Liens.

     8.2. Administration of Accounts.

               8.2.1. Records and Schedules of Accounts. Each Obligor shall keep accurate and complete records of its Accounts and all payments and collections thereon and shall submit to Agent on such periodic basis as Agent shall request a sales and collections report for the preceding period, in form satisfactory to Agent. Each Obligor shall also provide to Agent on or before the 25th day of each month, a summary aging of all Accounts existing and lists specifying the names, outstanding face amounts of Accounts of the 10 Account Debtors owing the largest amounts of Accounts and of the 10 largest Approved Account Debtors, all as of the last day of such preceding month (collectively, the “Schedule of Accounts”). Each Obligor shall also provide to Agent, upon Agent’s request therefor, a detailed aged trial balance for all Accounts specifying the names, addresses, face value and dates of invoices and due dates for each Account Debtor on an Account so listed and copies of proof of delivery of Inventory and a copy of all documents, including repayment histories and present status reports relating to the Accounts on the Schedule of Accounts or the detailed aged trail balance and such other matters and information relating to the status of then existing Accounts as Agent shall reasonably request. In addition, if Accounts in an aggregate face amount in excess of $5,000,000 shall cease to be Eligible Accounts in whole or in part, Obligors shall notify Agent of such occurrence promptly (and in any event within 2 Business Days) after any Obligor’s having obtained knowledge of such occurrence and the Borrowing Base shall thereupon be adjusted to reflect such occurrence. Each Obligor shall deliver to Agent copies of invoices or invoice registers related to all of its Accounts.

               8.2.2. Discounts, Disputes and Returns. If any Obligor grants any discounts, allowances or credits that are not shown on the face of the invoice for the Account involved, such Obligor shall report such discounts, allowances or credits, as the case may be to Agent as part of the next required Schedule of Accounts. If any amounts due and owing in excess of $2,500,000 are in dispute between any Obligor and any Account Debtor, or if any returns are made in excess of $2,500,000 with respect to any Accounts owing from an Account Debtor, such Obligor shall provide Agent with written notice thereof at the time of submission of the next Schedule of Accounts, explaining in detail the reason for the dispute or return, all claims related thereto and the amount in controversy. At any time an Event of Default exists, Agent shall have the right to settle or adjust all disputes and claims directly with the Account Debtor and to compromise the amount or extend the time for payment of any Accounts comprising a part of the Collateral upon such terms and conditions as Agent may deem advisable, and to charge the deficiencies, costs and expenses thereof, including attorneys’ fees, to Borrowers.

               8.2.3. Taxes. If an Account of any Obligor includes a charge for any Taxes payable to any Governmental Authority, Agent is authorized, in its sole discretion, to pay the amount thereof to the proper taxing authority for the account of such Obligor and to charge Borrowers therefor; provided, however, that neither Agent nor Lenders shall be liable for any Taxes that may be due by Obligors.

               8.2.4. Account Verification. Whether or not a Default or an Event of Default exists, Agent shall have the right at any time, in the name of Agent, any designee of Agent or any Obligor to verify the validity, amount or any other matter relating to any Accounts of such Obligor by mail, telephone, telegraph or otherwise. Obligors shall cooperate fully with Agent in an effort to facilitate and promptly conclude any such verification process.

               8.2.5. Maintenance of Dominion Account; Trigger Events.

          (i) At all times after the occurrence of a Trigger Event (as defined below), Borrowers shall maintain with a Clearing Bank a Dominion Account pursuant to a Lockbox Agreement or other arrangement acceptable to Agent. Borrowers shall issue to each such Clearing Bank an irrevocable letter of instruction directing such bank to deposit all payments or other remittances received in the Lockbox to the Dominion Account after the occurrence of a Trigger Event. Borrowers shall enter into agreements, in form satisfactory to Agent, with each bank at which a Dominion Account is maintained by which such bank shall, after the occurrence of a Trigger Event immediately transfer to the Payment Account all monies deposited to the Dominion Account. All funds deposited in each Dominion Account shall be subject to Agent’s Lien. Borrowers shall obtain the agreement (in favor of and in form and content satisfactory to Agent and Lenders) by each bank at which a Dominion Account is maintained to waive any offset rights against the funds deposited into such Dominion Account, except offset rights in respect of charges incurred in the administration of such Dominion Account. Neither Agent nor Lenders assume any responsibility to Borrowers for such lockbox arrangement or Dominion Account, including any claim of accord and satisfaction or release with respect to deposits accepted by any bank thereunder.

          (ii) If at any time Availability is less than an amount equal to the greater of (A) $20,000,000 or (B) ten percent (10%) of Availability (without requiring deduction of the LC Reserve in the calculation thereof) on any date, or if an Event of Default exists (each, a “Trigger Event”), without limiting the right of Agent and the Lenders to exercise other rights and remedies as a result thereof, Agent may require (and at the direction of the Required Lenders, shall require) that all collected balances in each Controlled Account be transferred to Agent not less often than each Business Day and that any or all of the Borrowers establish Lockboxes to which monies, checks, notes, drafts and other payments relating to or constituting proceeds of Collateral shall be sent.

               8.2.6. Collection of Accounts and Proceeds of Collateral. To expedite collection of Accounts, each Obligor shall endeavor, at such Obligor’s expense, in the first instance to make collection of such Obligor’s Accounts for Agent and Lenders and, in connection therewith, shall use commercially reasonable efforts to keep in full force and effect any Supporting Obligation or collateral security relating to each such Account. Obligors shall (i) request in writing and otherwise take such reasonable steps to ensure that all Account Debtors forward payment, after the occurrence of a Trigger Event, directly to the Dominion Account or to Lockboxes related to the Dominion Account, and (ii) deposit and cause its Subsidiaries to deposit or cause to be deposited promptly, and in any event no later than the first Business Day after the date of receipt thereof, all cash, checks, drafts or other similar items of payment relating to or constituting payments made in respect of any and all Collateral (whether or not otherwise delivered to a Lockbox), after the occurrence of a Trigger Event, into the Dominion Account. Obligors shall issue to each Lockbox bank an irrevocable letter of instruction directing such bank to deposit all payments or other remittances received in the Lockbox, after the occurrence of a Trigger Event, to the Dominion Account, with respect to remittances received in a Borrower’s Lockbox. All Payment Items received by any Obligor in respect of its Accounts, together with the proceeds of any other Collateral, shall be held by such Obligor as trustee of an express trust for Agent’s and Lenders’ benefit; such Obligor shall immediately deposit same in kind, after the occurrence of a Trigger Event with respect to Payment Items received by an Obligor, in the Dominion Account; and Agent may remit such proceeds received in the Dominion Account to Lenders for application to the Obligations in the manner authorized by this Agreement. Agent retains the right at all times that a Default or an Event of Default exists to notify Account Debtors of any Obligor that Accounts have been assigned to Agent and to collect Accounts directly in its own name and to charge to Obligors the collection costs and expenses incurred by Agent, including reasonable attorneys’ fees.

     8.3. Administration of Inventory.

               8.3.1. Records and Reports of Inventory. Each Obligor shall keep accurate and complete records of its Inventory (including records showing the cost thereof and daily withdrawals therefrom and additions thereto) and shall furnish Agent inventory reports respecting such Inventory in form and detail satisfactory to Agent at such times as Agent may request, but so long as no Default or Event of Default exists, no more frequently than once each week. Each Obligor shall, at its own expense, conduct a physical inventory no less frequently than annually (and on a more frequent basis if requested by Agent when an Event of Default exists) and periodic cycle counts consistent with such Obligor’s historical practices and shall provide to Agent a report based on each such physical inventory and cycle count promptly after completion thereof, together with such supporting information as Agent shall request.

In no event shall the Borrowing Base on any date be deemed to exceed the amount of the Borrowing Base shown on the Borrowing Base Certificate last received by Agent prior to such date, as the calculation in such Borrowing Base Certificate may be adjusted from time to time by Agent as herein authorized.

SECTION 9. REPRESENTATIONS AND WARRANTIES

     9.1. General Representations and Warranties . To induce Agent, Syndication Agent and Lenders to enter into this Agreement and to make available the Commitments, each Obligor warrants and represents to Agent and Lenders that:

               9.1.1. Organization and Qualification. Each Obligor and each of its Subsidiaries is an entity duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization. Each Obligor and each of its Subsidiaries is duly qualified and is authorized to do business and is in good standing as a foreign corporation in each state or jurisdiction listed on Schedule 9.1.1 hereto and in all other states and jurisdictions in which the failure of such Obligor or any of such Subsidiaries to be so qualified would have a Material Adverse Effect.

               9.1.2. Power and Authority. Each Obligor and each of its Subsidiaries is duly authorized and has the corporate, limited liability or other entity power, as the case may be, to enter into, execute, deliver and perform this Agreement and each of the other Loan Documents to which it is a party.

The execution, delivery and performance of this Agreement and each of the other Loan Documents have been duly authorized by all necessary entity action and do not and will not (i) require any consent or approval of any of the holders of the Equity Interests of any Obligor or any of its Subsidiaries other than those obtained on or prior to the date hereof; (ii) contravene the Organic Documents of any Obligor or any of its Subsidiaries; (iii) violate, or cause any Obligor or any of its Subsidiaries to be in default under, any provision of any Applicable Law, order, writ, judgment, injunction, decree, determination or award in effect having applicability to any Obligor or any of its Subsidiaries, in each case where such violation or default could reasonably be expected to have a Material Adverse Effect; (iv) result in a breach of or constitute a default under any indenture or loan or credit agreement or any other agreement, lease or instrument to which any Obligor or any of its Subsidiaries is a party or by which it or its Properties may be bound or affected; or (v) result in, or require, the creation or imposition of any Lien (other than Permitted Liens) upon or with respect to any of the Properties now owned or hereafter acquired by any Obligor or any of its Subsidiaries.

               9.1.3. Legally Enforceable Agreement. This Agreement is, and each of the other Loan Documents when delivered under this Agreement will be, a legal, valid and binding obligation of each Obligor and each of its Subsidiaries signatories thereto enforceable against them in accordance with the respective terms of such Loan Documents, except as the enforceability thereof may be limited by bankruptcy, insolvency or other similar laws of general application affecting the enforcement of creditors’ rights.

               9.1.4. Capital Structure. As of the date hereof, Schedule 9.1.4 hereto states (i) the correct name of each Obligor, its jurisdiction of formation and the percentage of its Equity Interests having voting powers owned by each Person, (ii) the name of each Obligor’s corporate Affiliates and the nature of the affiliation and (iii) the number of authorized and issued Equity Interests (and treasury shares) of each Obligor and its Subsidiaries. Each Obligor has good title to all of the shares it purports to own of the Equity Interests of each of its Subsidiaries, free and clear in each case of any Lien other than Permitted Liens. All such Equity Interests have been duly issued and are fully paid and non-assessable. Since the date of the financial statements of Borrowers referred to in Section 9.1.9 hereof, no Borrower has made, or obligated itself to make, any Distribution. There are no outstanding options to purchase, or any rights or warrants to subscribe for, or any commitments or agreements to issue or sell, or any Equity Interests or obligations convertible into, or any powers of attorney relating to, shares of the capital stock of any Obligor or any of its Subsidiaries. Except as set forth on Schedule 9.1.4 hereto, there are no outstanding agreements or instruments binding upon the holders of any Obligor’s Equity Interests relating to the ownership of its Equity Interests.

               9.1.5. Corporate Names. During the 5-year period preceding the date of this Agreement, no Obligor nor any of its Subsidiaries has been known as or used any corporate, fictitious or trade names except those listed on Schedule 9.1.5 hereto.

Except as shown on Schedule 8.1.1 on the date hereof, no Inventory of any Obligor or any of its Subsidiaries is stored with a bailee, warehouseman or similar Person, nor is any Inventory consigned to any Person.

               9.1.7. Title to Properties; Priority of Liens. Each Obligor and each of its Subsidiaries has good and marketable title to and fee simple ownership of, or valid and subsisting leasehold interests in, all of its real Property, and good title to all of its personal Property, including all Property reflected in the financial statements referred to in Section 9.1.9 or delivered pursuant to Section 10.1.3, in each case free and clear of all Liens except Permitted Liens. Each Obligor has paid or discharged, and has caused each of its Subsidiaries to pay and discharge, all lawful claims which, if unpaid, might become a Lien against any Properties of such Obligor or any such Subsidiary that is not a Permitted Lien. The Liens granted to Agent pursuant to this Agreement and the other Security Documents are duly perfected, first priority Liens, subject only to those Permitted Liens that are expressly permitted by the terms of this Agreement to have priority over the Liens of Agent.

               9.1.8. Accounts. Agent may rely, in determining which Accounts are Eligible Accounts, on all statements and representations made by Obligors with respect to any Account. Unless otherwise indicated in writing to Agent, with respect to each Account, each Borrower warrants that:

               (i) It is genuine and in all respects what it purports to be, and it is not evidenced by a judgment;

               (ii) It arises out of a completed, bona fide sale and delivery of goods or rendition of services by an Obligor in the Ordinary Course of Business and substantially in accordance with the terms and conditions of all purchase orders, contracts or other documents relating thereto and forming a part of the contract between an Obligor and the Account Debtor;

               (iii) It is for a sum certain maturing as stated in the duplicate invoice covering such sale or rendition of services, a copy of which has been furnished or is available to Agent on request;

               (iv) Such Account, and Agent’s security interest therein, is not, and will not (by voluntary act or omission of an Obligor) be in the future, subject to any offset (except with respect to Accounts for which DirecTV is the Account Debtor, to the extent such offset is adequately reserved for in the DirecTV Reserve), Lien, deduction, defense, dispute, counterclaim or any other adverse condition except for disputes resulting in returned goods where the amount in controversy is deemed by Agent to be immaterial, and each such Account is absolutely owing to an Obligor and is not contingent in any respect or for any reason;

               (v) The contract under which such Account arose does not condition or restrict an Obligor’s right to assign to Agent the right to payment thereunder unless such Obligor has obtained the Account Debtor’s consent to such collateral assignment or complied with any conditions to such assignment (regardless of whether under the UCC or other Applicable Law any such restrictions are ineffective to prevent the grant of a Lien upon such Account in favor of Agent);

               (vi) Such Obligor has not made any agreement with any Account Debtor thereunder for any extension, compromise, settlement or modification of any such Account or any deduction therefrom, except discounts or allowances which are granted by an Obligor in the Ordinary Course of Business for prompt payment and which are reflected in the calculation of the net amount of each respective invoice related thereto and are reflected in the Schedules of Accounts submitted to Agent pursuant to Section 8.2.1 hereof;

               (vii) To the best of such Obligor’s knowledge, there are no facts, events or occurrences which are reasonably likely to impair the validity or enforceability of such Account

or reduce the amount payable thereunder from the face amount of the invoice and statements delivered to Agent with respect thereto;

               (viii) To the best of such Obligor’s knowledge, the Account Debtor thereunder (1) had the capacity to contract at the time any contract or other document giving rise to the Account was executed and (2) is Solvent; and

               (ix) To the best of such Obligor’s knowledge, there are no proceedings or actions which are threatened or pending against any Account Debtor thereunder and which are reasonably likely to result in any material adverse change in such Account Debtor’s financial condition or the collectibility of such Account.

               9.1.9. Financial Statements; Fiscal Year. The Consolidated and consolidating balance sheets of Borrowers and such other Persons described therein (including the accounts of all Subsidiaries of Borrowers for the respective periods during which a Subsidiary relationship existed) as of December 31, 2004, and the related statements of income, changes in stockholder’s equity, and changes in financial position for the periods ended on such dates, have been prepared in accordance with GAAP, and present fairly the financial positions of Borrowers and such Persons at such dates and the results of Borrowers’ operations for such periods.

Any such deposit or advance shall be held by Agent in the Cash Collateral Account to fund future payments on any Letter of Credit.

Borrowers or any other Person (any such notice being hereby expressly waived), to set off and to appropriate and apply any and all deposits, general or special (including Debt evidenced by certificates of deposit whether matured or unmatured (but not including trust accounts)) and any other Debt at any time held or owing by such Lender or any of their Affiliates to or for the credit or the account of any Obligor against and on account of the Obligations of Obligors arising under the Loan Documents to Agent, such Lender or any of their Affiliates, including all Loans and LC Obligations and all claims of any nature or description arising out of or in connection with this Agreement, irrespective of whether or not (i) Agent or such Lender shall have made any demand hereunder, (ii) Agent, at the request or with the consent of the Required Lenders, shall have declared the principal of and interest on the Loans and other amounts due hereunder to be due and payable as permitted by this Agreement and even though such Obligations may be contingent or unmatured or (iii) the Collateral for the Obligations is adequate. Notwithstanding the foregoing, each of Agent and Lenders agree with each other that it shall not, without the express consent of the Required Lenders, and that it shall (to the extent that it is lawfully entitled to do so) upon the request of the Required Lenders, exercise its setoff rights hereunder against any accounts of any Obligor now or hereafter maintained with Agent, such Lender or any Affiliate of any of them, but no Obligor shall have any claim or cause of action against Agent or any Lender for any setoff made without the consent of the Required Lenders and the validity of any such setoff shall not be impaired by the absence of such consent. If any party (or its Affiliate) exercises the right of setoff provided for hereunder, such party shall be obligated to share any such setoff in the manner and to the extent required by Section 13.5.

The rights and remedies of Agent and Lenders under this Agreement and the other Loan Documents shall be cumulative and not exclusive of any rights or remedies that Agent or any Lender would otherwise have.

          12.5.2. The failure or delay of Agent or any Lender to require strict performance by Obligors of any provision of any of the Loan Documents or to exercise or enforce any rights, Liens, powers or remedies under any of the Loan Documents or with respect to any Collateral shall not operate as a waiver of such performance, Liens, rights, powers and remedies, but all such requirements, Liens, rights, powers, and remedies shall continue in full force and effect until the Full Payment of all Loans and all other Obligations owing or to become owing from Obligors to Agent and Lenders. None of the undertakings, agreements, warranties, covenants and representations of Obligors contained in this Agreement or any of the other Loan Documents and no Event of Default by any Obligor under this Agreement or any other Loan Documents shall be deemed to have been suspended or waived by Agent or any Lender, unless such suspension or waiver is by an instrument in writing specifying such suspension or waiver and is signed by a duly authorized representative of Agent or such Lender and directed to Borrowers.

          12.5.3. If Agent or any Lender shall accept performance by an Obligor, in whole or in part, of any obligation that such Obligor is required by any of the Loan Documents to perform only when a Default or Event of Default exists, or if Agent or any Lender shall exercise any right or remedy under any of the Loan Documents that may not be exercised other than when a Default or Event of Default exists, Agent’s or Lender’s acceptance of such performance by an Obligor or Agent’s or Lender’s exercise of any such right or remedy shall not operate to waive any such Event

of Default or to preclude the exercise by Agent or any Lender of any other right or remedy, unless otherwise expressly agreed in writing by Agent or such Lender, as the case may be.

The duties of Agent shall be ministerial and administrative in nature, and Agent shall not have by reason of this Agreement or any other Loan Document a fiduciary relationship with any Lender (or any Lender’s participants). Unless and until its authority to do so is revoked in writing by Required Lenders, Agent alone shall be authorized to determine whether any Accounts, Fixed Assets or Real Estate constitute Eligible Accounts, Eligible Fixed Assets or Eligible Real Estate (basing such determination in each case upon the meanings given to such terms in Section 1), or whether to impose or release any reserve, and to exercise its own credit judgment in connection therewith, which determinations and judgments, if exercised in good faith, shall exonerate Agent from any liability to Lenders or any other Person for any errors in judgment.

          13.1.2. Agent (which term, as used in this sentence, shall include reference to Agent’s officers, directors, employees, attorneys, agents and Affiliates and to the officers, directors, employees, attorneys and agents of Agent’s Affiliates) shall not: (a) have any duties or responsibilities except those expressly set forth in this Agreement and the other Loan Documents or (b) be required to take, initiate or conduct any Enforcement Action (including any litigation, foreclosure or collection proceedings hereunder or under any of the other Loan Documents) except to the extent directed to do so by the Required Lenders during the continuance of any Event of

Default. The conferral upon Agent of any right hereunder shall not imply a duty on Agent’s part to exercise any such right unless instructed to do so by the Required Lenders in accordance with this Agreement.

          13.1.3. Agent may perform any of its duties by or through its agents and employees and may employ one or more Agent Professionals and shall not be responsible for the negligence or misconduct of any such Agent Professionals selected by it with reasonable care. Borrowers shall promptly (and in any event, on demand) reimburse Agent for all reasonable expenses (including all Extraordinary Expenses) incurred by Agent pursuant to any of the provisions hereof or of any of the other Loan Documents or in the execution of any of Agent’s duties hereby or thereby created or in the exercise of any right or power herein or therein imposed or conferred upon it or Lenders (excluding, however, general overhead expenses), and each Lender agrees promptly to pay to Agent, on demand, such Lender’s Pro Rata share of any such reimbursement for expenses (including Extraordinary Expenses) that is not timely made by Borrowers to Agent.

          13.1.4. The rights, remedies, powers and privileges conferred upon Agent hereunder and under the other Loan Documents may be exercised by Agent without the necessity of the joinder of any other parties unless otherwise required by Applicable Law. If Agent shall request instructions from the Required Lenders with respect to any act or action (including the failure to act) in connection with this Agreement or any of the other Loan Documents, Agent shall be entitled to refrain from such act or taking such action unless and until Agent shall have received instructions from the Required Lenders; and Agent shall not incur liability to any Person by reason of so refraining. Without limiting the foregoing, no Lender shall have any right of action whatsoever against Agent as a result of Agent acting or refraining from acting hereunder or under any of the Loan Documents pursuant to or in accordance with the instructions of the Required Lenders except for Agent’s own gross negligence or willful misconduct in connection with any action taken by it. Notwithstanding anything to the contrary contained in this Agreement, Agent shall not be required to take any action that is in its opinion contrary to Applicable Law or the terms of any of the Loan Documents or that would in its reasonable opinion subject it or any of its officers, employees or directors to personal liability.

          13.1.5. Agent shall promptly, upon receipt thereof, forward to each Lender (i) copies of any significant written notices, reports, certificates and other information received by Agent from any Obligor, including each Schedule of Accounts (but only if and to the extent such Obligor is not required by the terms of the Loan Documents to supply such information directly to Lenders) and (ii) copies of the results of any appraisals, or field audits by or other examinations made or prepared by or on behalf of Agent with respect to Obligors or the Collateral (each, a “Report” and collectively, “Reports”). Agent shall have no liability to any Lender for any errors in or omissions from any field audit or other examination of Obligors or the Collateral, unless such error or omission was the direct result of Agent’s willful misconduct or gross negligence.

     13.2. Agreements Regarding Collateral and Examination Reports.

          13.2.1. Lenders hereby irrevocably authorize Agent to release any Lien with respect to any Collateral (i) upon the termination of the Commitments and Full Payment of the Obligations, (ii) that is the subject of an Asset Disposition which Borrowers certify in writing to Agent is a Permitted Asset Disposition (and Agent may rely conclusively on any such certificate without further inquiry), or (iii) with the written consent of all Lenders. Agent shall have no obligation whatsoever to any of the Lenders to assure that any of the Collateral exists or is owned by an Obligor or is cared for, protected or insured or has been encumbered, or that Agent’s Liens have been properly, sufficiently or lawfully created, perfected, protected or enforced or entitled to any particular priority or to exercise any duty of care with respect to any of the Collateral.

          13.2.2. Each Lender agrees that neither BofA nor Agent makes any representation or warranty as to the accuracy or completeness of any Report and shall not be liable for any information contained in or omitted from any such Report; agrees that the Reports are not intended to be comprehensive audits or examinations and that BofA or Agent or any other Person performing any audit or examination will inspect only specific information regarding Obligations or the Collateral and will rely significantly upon Borrowers’ books and records as well as upon representations of Borrowers’ officers and employees; agrees to keep all Reports confidential and strictly for its internal use and not to distribute the Reports (or the contents thereof) to any Person (except to its Participants, attorneys, accountants and other Persons with whom such Lender has a confidential relationship) or use any Report in any other manner; and, without limiting the generality of any other indemnification contained herein, agrees to hold Agent and any other Person preparing a Report harmless from any action that the indemnifying Lender may take or conclusion the indemnifying Lender may reach or draw from any Report in connection with any Loans or other credit accommodations that the indemnifying Lender has made or may make to Borrowers, or the indemnifying Lender’s participation in, or its purchase of, a loan or loans of any Obligor, and to pay and protect, and indemnify, defend and hold Agent and each other such Person preparing a Report harmless from and against all claims, actions, proceedings, damages, costs, expenses and other amounts (including attorneys’ fees incurred by Agent and any such other Person preparing a Report as the direct or indirect result of any third parties who might obtain all or any part of any Report through the indemnifying Lender.

     13.3. Reliance By Agent. Agent shall be entitled to rely, and shall be fully protected in so relying, upon any certification, notice or other communication (including any thereof by telephone, telex, telegram, telecopier message or cable) believed by it to be genuine and correct and to have been signed, sent or made by or on behalf of the proper Person or Persons, and upon advice and statements of Agent Professionals selected by Agent. Without limiting the generality of the foregoing, Agent may rely upon any Notice of Borrowing, LC Request, Notice of Conversion/Continuance or any similar notice or request believed by Agent to be genuine. As to any matters not expressly provided for by this Agreement or any of the other Loan Documents, Agent shall in all cases be fully protected in acting or refraining from acting hereunder and thereunder in accordance with the instructions of the Required Lenders, and such instructions of the Required Lenders and any action taken or failure to act pursuant thereto shall be binding upon Lenders.

     13.4. Action Upon Default. Agent shall not be deemed to have knowledge of the occurrence of a Default or an Event of Default unless it has received written notice from a Lender or any or all Borrowers specifying the occurrence and nature of such Default or Event of Default. If Agent shall receive such a notice of a Default or an Event of Default or shall otherwise acquire actual knowledge of any Default or Event of Default, Agent shall promptly notify Lenders in writing and Agent shall take such action and assert such rights under this Agreement and the other Loan Documents, or shall refrain from

taking such action and asserting such rights, as the Required Lenders shall direct from time to time. If any Lender shall receive a notice of a Default or an Event of Default or shall otherwise acquire actual knowledge of any Default or Event of Default, such Lender shall promptly notify Agent and the other Lenders in writing. As provided in Section 13.3 hereof, Agent shall not be subject to any liability by reason of acting or refraining to act pursuant to any request of the Required Lenders except for its own willful misconduct or gross negligence in connection with any action taken by it. Before directing Agent to take or refrain from taking any action or asserting any rights or remedies under this Agreement and the other Loan Documents on account of any Event of Default, the Required Lenders shall consult with and seek the advice of (but without having to obtain the consent of) each other Lender, and promptly after directing Agent to take or refrain from taking any such action or asserting any such rights, the Required Lenders will so advise each other Lender of the action taken or refrained from being taken and, upon request of any Lender, will supply information concerning actions taken or not taken. In no event shall the Required Lenders, without the prior written consent of each Lender, direct Agent to accelerate and demand payment of the Loans held by one Lender without accelerating and demanding payment of all other Loans or to terminate the Commitments of one or more Lenders without terminating the Commitments of all Lenders. Each Lender agrees that, except as otherwise provided in any of the Loan Documents or with the written consent of Agent and the Required Lenders, it will not take any legal action or institute any action or proceeding against any Obligor with respect to any of the Obligations or Collateral or accelerate or otherwise enforce its portion of the Obligations. Without limiting the generality of the foregoing, none of Lenders may exercise any right that it might otherwise have under Applicable Law to credit bid at foreclosure sales, UCC sales, PPSA sales or other similar sales or dispositions of any of the Collateral except as authorized by Agent and Required Lenders. Notwithstanding anything to the contrary set forth in this Section 13.4 or elsewhere in this Agreement, each Lender shall be authorized to take such action to preserve or enforce its rights against any Obligor where a deadline or limitation period is otherwise applicable and would, absent the taken of specified action, bar the enforcement of Obligations held by such Lender against such Obligor, including the filing of proofs of claim in any Insolvency Proceeding.

     13.5. Ratable Sharing. If any Lender shall obtain any payment or reduction (including any amounts received as adequate protection of a bank account deposit treated as cash collateral under the Bankruptcy Code) of any Obligation of Borrowers (whether voluntary, involuntary, through the exercise of any right of set-off or otherwise) in excess of its Pro Rata share of payments or reductions on account of such Obligations obtained by all of the Lenders, such Lender shall forthwith (i) notify the other Lenders and Agent of such receipt and (ii) purchase from the other Lenders such participations in the affected Obligations as shall be necessary to cause such purchasing Lender to share the excess payment or reduction, net of costs incurred in connection therewith, on a Pro Rata basis, provided that if all or any portion of such excess payment or reduction is thereafter recovered from such purchasing Lender or additional costs are incurred, the purchase shall be rescinded and the purchase price restored to the extent of such recovery or such additional costs, but without interest. Each Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 13.5 may, to the fullest extent permitted by Applicable Law, exercise all of its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of Borrowers in the amount of such participation.

     13.6. Indemnification of Agent Indemnitees.

          13.6.1. Each Lender agrees to indemnify and defend the Agent Indemnitees (to the extent not reimbursed by Borrowers, but without limiting the indemnification obligations of Borrowers under any of the Loan Documents), on a Pro Rata basis, and to hold each of the Agent Indemnitees harmless from and against, any and all Indemnified Claims which may be imposed on, incurred by or asserted against any of the Agent Indemnitees in any way related to or arising out of

this Agreement or any of the other Loan Documents or any other document contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby (including the costs and expenses which Borrowers are obligated to pay under Section 15.2 hereof or amounts Agent may be called upon to pay in connection with any lockbox or Dominion Account arrangement contemplated hereby or under any indemnity, guaranty or other assurance of payment or performance given by Agent pursuant to Section 3.4.2 or the enforcement of any of the terms hereof or thereof or of any such other documents, provided that no Lender shall be liable to an Agent Indemnitee for any of the foregoing to the extent that they result solely from the willful misconduct or gross negligence of such Agent Indemnitee.

          13.6.2. Without limiting the generality of the foregoing provisions of this Section 13.6, if Agent should be sued by any receiver, trustee in bankruptcy, debtor-in-possession or other Person on account of any alleged preference or fraudulent transfer received or alleged to have been received from any Borrower or any other Obligor as the result of any transaction under the Loan Documents, then in such event any monies paid by Agent in settlement or satisfaction of such suit, together with all Extraordinary Expenses incurred by Agent in the defense of same, shall be promptly reimbursed to Agent by Lenders to the extent of each Lender’s Pro Rata share.

          13.6.3. Without limiting the generality of the foregoing provisions of this Section 13.6, if at any time (whether prior to or after the Commitment Termination Date) any action or proceeding shall be brought against any of the Agent Indemnitees by an Obligor or by any other Person claiming by, through or under an Obligor, to recover damages for any act taken or omitted by Agent under any of the Loan Documents or in the performance of any rights, powers or remedies of Agent against any Obligor, any Account Debtor, the Collateral or with respect to any Loans, or to obtain any other relief of any kind on account of any transaction involving any Agent Indemnitees under or in relation to any of the Loan Documents, each Lender agrees to indemnify, defend and hold the Agent Indemnitees harmless with respect thereto and to pay to the Agent Indemnitees such Lender’s Pro Rata share of such amount as any of the Agent Indemnitees shall be required to pay by reason of a judgment, decree, or other order entered in such action or proceeding or by reason of any compromise or settlement agreed to by the Agent Indemnitees, including all interest and costs assessed against any of the Agent Indemnitees in defending or compromising such action, together with attorneys’ fees and other legal expenses paid or incurred by the Agent Indemnitees in connection therewith; provided, however, that no Lender shall be liable to any Agent Indemnitee for any of the foregoing to the extent that they arise solely from the willful misconduct or gross negligence of such Agent Indemnitee. In Agent’s discretion, Agent may also reserve for or satisfy any such judgment, decree or order from proceeds of Collateral prior to any distributions therefrom to or for the account of Lenders.

     13.7. Limitation on Responsibilities of Agent. Agent shall in all cases be fully justified in failing or refusing to act hereunder unless it shall have received further assurances to its satisfaction from Lenders of their indemnification obligations under Section 13.6 hereof against any and all Indemnified Claims which may be incurred by Agent by reason of taking or continuing to take any such action. Agent shall not be liable to Lenders for any action taken or omitted to be taken under or in connection with this Agreement or the other Loan Documents except as a result and to the extent of losses caused by Agent’s actual gross negligence or willful misconduct. Agent does not assume any responsibility for any failure or delay in performance or breach by any Obligor or any Lender of its obligations under this Agreement or any of the other Loan Documents. Agent does not make to Lenders, and no Lender makes to Agent or the other Lenders, any express or implied warranty, representation or guarantee with respect to any Obligations, the Collateral, the Loan Documents or any Obligor. Neither Agent nor any of its officers, directors, employees, attorneys or agents shall be responsible to Lenders, and no Lender nor any of its agents, attorneys or employees shall be responsible to Agent or the other Lenders, for: (i) any recitals,

statements, information, representations or warranties contained in any of the Loan Documents or in any certificate or other document furnished pursuant to the terms hereof; (ii) the execution, validity, genuineness, effectiveness or enforceability of any of the Loan Documents; (iii) the validity, genuineness, enforceability, collectibility, value, sufficiency or existence of any Collateral, or the perfection or priority of any Lien therein; or (iv) the assets, liabilities, financial condition, results of operations, business, creditworthiness or legal status of any Obligor or any Account Debtor. Neither Agent nor any of its officers, directors, employees, attorneys or agents shall have any obligation to any Lender to ascertain or inquire into the existence of any Default or Event of Default, the observance or performance by any Obligor of any of the duties or agreements of such Obligor under any of the Loan Documents or the satisfaction of any conditions precedent contained in any of the Loan Documents. Agent may consult with and employ legal counsel, accountants and other experts and shall be entitled to act upon, and shall be fully protected in any action taken in good faith reliance upon, any advice given by such experts.

     13.8. Successor Agent and Co-Agents.

          13.8.1. Subject to the appointment and acceptance of a successor Agent as provided below, Agent may resign at any time by giving at least 30 days written notice thereof to each Lender and Borrowers. Upon receipt of any notice of such resignation, the Required Lenders, after prior consultation with (but without having to obtain consent of) each Lender, shall have the right to appoint a successor Agent which shall be (i) a Lender, (ii) a United States based affiliate of a Lender, or (iii) a commercial bank that is organized under the laws of the United States or of any State thereof and has a combined capital surplus of at least $200,000,000 and, provided no Default or Event of Default then exists, is reasonably acceptable to Borrowers (and for purposes hereof, any successor to BofA shall be deemed acceptable to Borrowers). If no successor agent is appointed prior to the effective date of the resignation of Agent, then Agent may appoint, after consultation with Lenders and Borrower Agent, a successor agent from among Lenders. Upon the acceptance by a successor Agent of an appointment to serve as an Agent hereunder, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent without further act, deed or conveyance, and the retiring Agent shall be discharged from its duties and obligations hereunder but shall continue to enjoy the benefits of the indemnification set forth in Sections 13.6 and 15.2 hereof. After any retiring Agent’s resignation hereunder as Agent, the provisions of this Section 13 (including the provisions of Section 13.6 hereof) shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Agent. Notwithstanding anything to the contrary contained in this Agreement, any successor by merger or acquisition of the stock or assets of BofA shall continue to be Agent hereunder without further act on the part of the parties hereto unless such successor shall resign in accordance with the provisions hereof.

          13.8.2. It is the intent of the parties that there shall be no violation of any Applicable Law denying or restricting the right of financial institutions to transact business as agent or otherwise in any jurisdiction. In case of litigation under any of the Loan Documents, or in case Agent deems that by reason of present or future laws of any jurisdiction Agent might be prohibited from exercising any of the powers, rights or remedies granted to Agent or Lenders hereunder or under any of the Loan Documents or from holding title to or a Lien upon any Collateral or from taking any other action which may be necessary hereunder or under any of the Loan Documents, Agent may appoint an additional Person as a separate collateral agent or co-collateral agent which is not so prohibited from taking any of such actions or exercising any of such powers, rights or remedies. If Agent shall appoint an additional Person as a separate collateral agent or co-collateral agent as provided above, each and every remedy, power, right, claim, demand or cause of action intended by any of the Loan Documents to be exercised by or vested in or conveyed to Agent with respect thereto shall be exercisable by and vested in such separate collateral agent or co-collateral

agent, but only to the extent necessary to enable such separate collateral agent or co-collateral agent to exercise such powers, rights and remedies, and every covenant and obligation necessary to the exercise thereof by such separate collateral agent or co-collateral agent shall run to and be enforceable by either of them. Should any instrument from Lenders be required by the separate collateral agent or co-collateral agent so appointed by Agent in order more fully and certainly to vest in and confirm to him or it such rights, powers, duties and obligations, any and all of such instruments shall, on request, be executed, acknowledged and delivered by Lenders whether or not a Default or Event of Default then exists. In case any separate collateral agent or co-collateral agent, or a successor to either, shall die, become incapable of acting, resign or be removed, all the estates, properties, rights, powers, duties and obligations of such separate collateral agent or co-collateral agent, so far as permitted by Applicable Law, shall vest in and be exercised by Agent until the appointment of a new collateral agent or successor to such separate collateral agent or co-collateral agent.

     13.9. Consents, Amendments and Waivers; Out-of-Formula Loans.

          13.9.1. No amendment or modification of any provision of this Agreement or any of the other Loan Documents, nor any waiver of any Default or Event of Default, shall be effective without the prior written agreement or consent of the Required Lenders; provided, however, that

          (i) without the prior written consent of Agent, no amendment or waiver shall be effective with respect to any provision in any of the Loan Documents (including Section 3.4 and this Section 13) to the extent such provision relates to the rights, duties, immunities, exculpation, indemnification or discretion of Agent;

          (ii) without the prior written consent of Issuing Bank, no amendment or waiver with respect to any of the LC Obligations or the provisions of Sections 2.3, 4.1.3 or 11.2.6 shall be effective;

          (iii) without the prior written consent of each affected Lender, no amendment or waiver shall be effective that would (1) increase or otherwise modify any Commitment of such Lender (other than (x) to reduce such Lender’s Commitment on a proportionate basis with the same Commitments of other Lenders, or (y) pursuant to Section 2.1.6 hereof); (2) alter (other than to increase) the rate of interest or any fee payable in respect of any Obligations owed to such Lender; (3) waive or defer collection of any interest or fee payable to such Lender pursuant to Section 3; or (4) subordinate the payment of any Obligations owed to such Lender to the payment of any Debt (except as expressly provided in Section 5.6.1); and

          (iv) without the prior written consent of all Lenders (except a defaulting Lender as provided in Section 4.2 of this Agreement), no amendment or waiver shall be effective that would (1) waive any Default or Event of Default if the Default or Event of Default relates to any Borrower’s failure to observe or perform any covenant that may not be amended without the unanimous written consent of Lenders (and, where so provided hereinafter, the written consent of Agent) as hereinafter set forth; (2) alter the provisions of Sections 3.6, 3.7, 3.8, 3.10, 5.6, 5.7, 7.1 (except to add to the categories of Property of Borrowers constituting Collateral), 8.4.4, 8.6, 13.9, 15.2, 15.3, 15.4 or 15.16; (3) amend the definitions (and the other defined terms used in such definitions) of “Pro Rata,” “Required Lenders,” “Eligible Assignee,” “Obligations,” “Availability Reserve” or “Borrowing Base”, or any provision of this Agreement obligating Agent to take certain actions at the direction of the Required Lenders, or any provision of any of the Loan Documents regarding the Pro Rata treatment or obligations of Lenders; (4) subordinate the priority of any Liens granted to Agent under any of the Loan Documents to consensual, non-statutory Liens granted after the Closing Date to any other Person, except as currently provided in or contemplated by the Loan Documents (including a subordination in favor of the holders of

Permitted Liens that have priority over Agent’s Liens under Applicable Law) and except for Liens granted by an Obligor to financial institutions with respect to amounts on deposit with such financial institutions to cover returned items, processing and analysis charges and other charges in the Ordinary Course of Business that relate to deposit accounts with such financial institutions, or (5) alter the time (other than to accelerate or make more frequent) or amount (other than to increase the amount to be repaid) of repayment of any of the Loans or waive any Event of Default resulting from nonpayment of the Loans on the due date thereof (or within any applicable period of grace), or (6) release any Obligor that is Solvent from liability for any of the Obligations.

          Notwithstanding the foregoing, the consent or agreement of Borrowers shall not be necessary to the effectiveness of any amendment or waiver of any provision of this Agreement that deals solely with the rights and duties of Lenders and Agent as among themselves, including Sections 5.6.1 and 15. The making of any Loans hereunder by any Lender during the existence of a Default or Event of Default shall not be deemed to constitute a waiver of such Default or Event of Default. Any waiver or consent granted by Lenders hereunder shall be effective only if in writing and then only in the specific instance and for the specific purpose for which it was given.

          13.9.2. No Borrower will, directly or indirectly, pay or cause to be paid any remuneration or other thing of value, whether by way of supplemental or additional interest, fee or otherwise, to any Lender (in its capacity as a Lender hereunder) as consideration for or as an inducement to the consent to or agreement by such Lender with any waiver or amendment of any of the terms and provisions of this Agreement or any of the other Loan Documents to the extent that the agreement of all Lenders to any such waiver or amendment is required, unless such remuneration or thing of value is concurrently paid, on the same terms, on a Pro Rata or other mutually agreed upon basis to all Lenders; provided, however, that Borrowers may contract to pay a fee only to those Lenders who actually vote in writing to approve any waiver or amendment of the terms and provisions of this Agreement or any of the other Loan Documents to the extent that such waiver or amendment may be implemented by vote of the Required Lenders and such waiver or amendment is in fact approved.

          13.9.3. Any request, authority or consent of any Person who, at the time of making such request or giving such a authority or consent, is a Lender, shall be conclusive and binding upon any Transferee of such Lender.

          13.9.4. Unless otherwise directed in writing by the Required Lenders, Agent may require Lenders to honor requests by Borrowers for Out-of-Formula Loans (in which event, and notwithstanding anything to the contrary set forth in Section 2.1.1 or elsewhere in this Agreement, Lenders shall continue to make Revolver Loans up to their Pro Rata share of the Commitments) and to forbear from requiring Borrowers to cure an Out-of-Formula Condition, (1) when no Event of Default exists (or if an Event of Default exists, when the existence of such Event of Default is not known by Agent), if and for so long as (i) such Out-of-Formula Condition does not continue for a period of more than 10 consecutive Business Days, following which no Out-of-Formula Condition exists for at least 10 consecutive Business Days before another Out-of-Formula Condition exists, (ii) the amount of the Revolver Loans outstanding at any time does not exceed the aggregate of the Commitments at such time, and (iii) the Out-of-Formula Condition is not known by Agent at the time in question to exceed $5,000,000; and (2) regardless of whether or not an Event of Default exists, if Agent discovers the existence of an Out-of-Formula Condition not previously known by it to exist, but Lenders shall be obligated to continue making such Revolver Loans as directed by Agent only (A) if the amount of the Out-of-Formula Condition is not increased by more than $5,000,000 above the amount determined by Agent to exist on the date of discovery thereof and (B) for a period not to exceed 5 Business Days. In no event shall any Borrower or any other Obligor

be deemed to be a beneficiary of this Section 13.9.4 or authorized to enforce any of the provisions of this Section 13.9.4.

     13.10. Due Diligence and Non-Reliance. Each Lender hereby acknowledges and represents that it has, independently and without reliance upon Agent, Syndication Agent or the other Lenders, and based upon such documents, information and analyses as it has deemed appropriate, made its own credit analysis of each Obligor and its own decision to enter into this Agreement and to fund the Loans to be made by it hereunder and to purchase participations in the LC Obligations pursuant to Section 2.3.2 hereof, and each Lender has made such inquiries concerning the Loan Documents, the Collateral and each Obligor as such Lender feels necessary and appropriate, and has taken such care on its own behalf as would have been the case had it entered into the other Loan Documents without the intervention or participation of the other Lenders or Agent. Each Lender hereby further acknowledges and represents that the other Lenders, Syndication Agent and Agent have not made any representations or warranties to it concerning any Obligor, any of the Collateral or the legality, validity, sufficiency or enforceability of any of the Loan Documents. Each Lender also hereby acknowledges that it will, independently and without reliance upon the other Lenders, Syndication Agent or Agent, and based upon such financial statements, documents and information as it deems appropriate at the time, continue to make and rely upon its own credit decisions in making Loans and in taking or refraining to take any other action under this Agreement or any of the other Loan Documents. Except for notices, reports and other information expressly required to be furnished to Lenders by Agent hereunder, Agent shall not have any duty or responsibility to provide any Lender with any notices, reports or certificates furnished to Agent by any Obligor or any credit or other information concerning the affairs, financial condition, business or Properties of any Obligor (or any of its Affiliates) which may come into possession of Agent or any of Agent’s Affiliates.

     13.11. Representations and Warranties of Lenders. Each Lender represents and warrants to each Borrower, Agent and the other Lenders that it has the power to enter into and perform its obligations under this Agreement and the other Loan Documents, and that it has taken all necessary and appropriate action to authorize its execution and performance of this Agreement and the other Loan Documents to which it is a party, each of which will be binding upon it and the obligations imposed upon it herein or therein will be enforceable against it in accordance with the respective terms of such documents; and none of the consideration used by it to make or fund its Loans or to participate in any other transactions under this Agreement constitutes for any purpose of ERISA or Section 4975 of the Internal Revenue Code assets of any “plan” as defined in Section 3(3) of ERISA or Section 4975 of the Internal Revenue Code and the rights and interests of such Lender in and under the Loan Documents shall not constitute plan assets under ERISA.

     13.12. The Required Lenders. As to any provisions of this Agreement or the other Loan Documents under which action may or is required to be taken upon direction or approval of the Required Lenders, the direction or approval of the Required Lenders shall be binding upon each Lender to the same extent and with the same effect as if each Lender joined therein. Notwithstanding anything to the contrary contained in this Agreement, Borrowers shall not be deemed to be a beneficiary of, or be entitled to enforce, sue upon or assert as a defense to any of the Obligations, any provisions of this Agreement that requires Agent or any Lender to act, or conditions their authority to act, upon the direction or consent of the Required Lenders; and any action taken by Agent or any Lender that requires the consent or direction of the Required Lenders as a condition to taking such action shall, insofar as Borrowers are concerned, be presumed to have been taken with the requisite consent or direction of the Required Lenders.

     13.13. Several Obligations. The obligations and commitments of each Lender under this Agreement and the other Loan Documents are several and neither Agent nor any Lender shall be responsible for the performance by the other Lenders of its obligations or commitments hereunder or

thereunder. Notwithstanding any liability of Lenders stated to be joint and several to third Persons under any of the Loan Documents, such liability shall be shared, as among Lenders, Pro Rata.

     13.14. Agent in its Individual Capacity. With respect to its obligation to lend under this Agreement, the Loans made by it and each Note issued to it, Agent shall have the same rights and powers hereunder and under the other Loan Documents as any other Lender or holder of a Note and may exercise the same as though it were not performing the duties specified herein; and the terms “Lenders,” “Required Lenders,” or any similar term shall, unless the context clearly otherwise indicates, include Agent in its capacity as a Lender. Agent and its Affiliates may each accept deposits from, maintain deposits or credit balances for, invest in, lend money to, act as trustee under indentures of, serve as financial advisor to, and generally engage in any kind of business with any Borrower or any other Obligor, or any affiliate of any Borrower or any other Obligor, as if it were any other bank and without any duty to account therefor (or for any fees or other consideration received in connection therewith) to the other Lenders. BofA or its affiliates may receive information regarding any Borrower or any of such Borrower’s Affiliates and account debtors (including information that may be subject to confidentiality obligations in favor of Borrowers or any of their Affiliates) and Lenders acknowledge that neither Agent nor BofA shall be under any obligation to provide such information to Lenders to the extent acquired by BofA in its individual capacity and not as Agent hereunder.

     13.15. No Third Party Beneficiaries. This Section 13 is not intended to confer any rights or benefits upon Borrowers or any other Person except Lenders and Agent, and no Person (including any or all Borrowers) other than Lenders and Agent shall have any right to enforce any of the provisions of this Section 13 except as expressly provided in Section 13.17 hereof. As between Obligors and Agent, any action that Agent may take or purport to take on behalf of Lenders under any of the Loan Documents shall be conclusively presumed to have been authorized and approved by Lenders as herein provided.

     13.16. Notice of Transfer. Agent may deem and treat a Lender party to this Agreement as the owner of such Lender’s portion of the Revolver Loans for all purposes, unless and until a written notice of the assignment or transfer thereof executed by such Lender has been received by Agent.

     13.17. Replacement of Certain Lenders. If a Lender (“Affected Lender”) shall have (i) failed to fund its Pro Rata share of any Loan requested (or deemed requested) by Borrowers which such Lender is obligated to fund under the terms of this Agreement and which such failure has not been cured, (ii) requested compensation from Borrowers under Section 3.7 or Section 3.8 to recover increased costs incurred by such Lender (or its parent or holding company) or compensation required by such Lender which are not being incurred or required generally by the other Lenders (or their respective parents or holding companies), (iii) delivered a notice pursuant to Section 3.6 hereof claiming that such Lender is unable to extend LIBOR Loans to Borrowers for reasons not generally applicable to the other Lenders, (iv) defaulted in paying or performing any of its obligations to Agent, or (v) failed or refused to give its consent to any amendment, waiver or action for which consent of all of the Lenders is required and in respect of which the Required Lenders have consented, then, in any such case and in addition to any other rights and remedies that Agent, any other Lender or any Borrower may have against such Affected Lender, any Borrower or Agent may make written demand on such Affected Lender (with a copy to Agent in the case of a demand by Borrowers and a copy to Borrowers in the case of a demand by Agent) for the Affected Lender to assign, and such Affected Lender shall assign pursuant to one or more duly executed Assignment and Acceptances within 5 Business Days after the date of such demand, to one or more Lenders willing to accept such assignment or assignments, or to one or more Eligible Assignees designated by Agent, all of such Affected Lender’s rights and obligations under this Agreement (including its Commitments and all Loans owing to it) in accordance with Section 14 hereof. Agent is hereby irrevocably authorized to execute one or more Assignment and Acceptances as attorney-in-fact for any Affected Lender which fails or refuses to execute and deliver the same within 5 Business Days after the

date of such demand. The Affected Lender shall be entitled to receive, in cash and concurrently with execution and delivery of each such Assignment and Acceptance, all amounts owed to the Affected Lender hereunder or under any other Loan Document, including the aggregate outstanding principal amount of the Loans owed to such Lender, together with accrued interest thereon through the date of such assignment (but excluding any prepayment penalty or termination charge). Upon the replacement of any Affected Lender pursuant to this Section 13.17, such Affected Lender shall cease to have any participation in, entitlement to, or other right to share in the Liens of Agent in any Collateral and such Affected Lender shall have no further liability to Agent, any Lender or any other Person under any of the Loan Documents (except as provided in Section 13.6 hereof as to events or transactions which occur prior to the replacement of such Affected Lender), including any Commitment to make Loans or purchase participations in LC Obligations. Agent shall have the right at any time, but shall not be obligated to, upon written notice to any Lender and with the consent of such Lender (which may be granted or withheld in such Lender’s sole discretion), to purchase for Agent’s own account all of such Lender’s right, title and interest in and to this Agreement, the other Loan Documents and the Obligations (together with such Lender’s interest in the Commitments), for the face amount of the Obligations owed to such Lender (or such greater or lesser amount as Agent and Lender may mutually agree upon).

     13.18. Remittance of Payments and Collections.

          13.18.1. All payments by any Lender to Agent shall be made not later than the time set forth elsewhere in this Agreement on the Business Day such payment is due; provided, however, that if such payment is due on demand by Agent and such demand is made on the paying Lender after 11:00 a.m. on such Business Day, then payment shall be made by 11:00 a.m. on the next Business Day. Payment by Agent to any Lender shall be made by wire transfer, promptly following Agent’s receipt of funds for the account of such Lender and in the type of funds received by Agent; provided, however, that if Agent receives such funds at or prior to 12:00 noon, Agent shall pay such funds to such Lender by 2:00 p.m. on such Business Day, but if Agent receives such funds after 12:00 noon, Agent shall pay such funds to such Lender by 2:00 p.m. on the next Business Day.

          13.18.2. With respect to the payment of any funds from Agent to a Lender or from a Lender to Agent, the party failing to make full payment when due pursuant to the terms hereof shall, on demand by the other party, pay such amount together with interest thereon at the Federal Funds Rate. In no event shall Borrowers be entitled to receive any credit for any interest paid by Agent to any Lender, or by any Lender to Agent, at the Federal Funds Rate as provided herein.

     If Agent pays any amount to a Lender in the belief or expectation that a related payment has been or will be received by Agent from an Obligor and such related payment is not received by Agent, then Agent shall be entitled to recover such amount from each Lender that receives such amount. If Agent determines at any time that any amount received by it under this Agreement or any of the other Loan Documents must be returned to an Obligor or paid to any other Person pursuant to any Applicable Law, court order or otherwise, then, notwithstanding any other term or condition of this Agreement or any of the other Loan Documents, Agent shall not be required to distribute such amount to any Lender.

     13.19. Syndication Agent. For avoidance of doubt, it is expressly acknowledged and agreed by Agent and each Lender for the benefit of Syndication Agent that, other than any rights or obligations explicitly reserved to or imposed upon Syndication Agent under this Agreement, Syndication Agent, in such capacity, has no rights or obligations hereunder nor shall Syndication Agent, in such capacity, be responsible or accountable to any other party hereto for any action or failure to act hereunder, other than in connection with such explicitly reserved rights or such obligations and then only for claims, damages, losses (other than consequential losses) and other liabilities arising out of Syndication Agent’s own gross negligence or willful misconduct.

SECTION 14. BENEFIT OF AGREEMENT; ASSIGNMENTS AND PARTICIPATIONS

     14.1. Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of Obligors, Agent, Syndication Agent and Lenders and their respective successors and assigns (which, in the case of Agent, shall include any successor Agent appointed pursuant to Section 13.8 hereof), except that (i) no Obligor shall have the right to assign its rights or delegate performance of any of its obligations under any of the Loan Documents and (ii) any assignment by any Lender must be made in compliance with Section 14.3. Agent may treat the Person which made any Loan or holds any Note as the owner thereof for all purposes hereof unless and until such Person complies with Section 14.3 in the case of an assignment thereof or, in the case of any other transfer, a written notice of the transfer is filed with Agent. Any assignee or transferee of any rights with respect to any Note or Loan agrees by acceptance thereof to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the holder of a Note, shall be conclusive and binding on any subsequent holder, transferee or assignee of such Note or of any Note or Notes issued in exchange therefor.

     14.2. Participations.

               14.2.1. Permitted Participants; Effect. Any Lender may, in the ordinary course of its business and in accordance with Applicable Law, at any time sell to one or more banks or other financial institutions (each a “Participant”) a participating interest in any of the Obligations owing to such Lender, any Commitment of such Lender or any other interest of such Lender under any of the Loan Documents. In the event of any such sale by a Lender of participating interests to a Participant, such Lender’s obligations under the Loan Documents shall remain unchanged, such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, such Lender shall remain the holder of its Loans and Commitments for all purposes under the Loan Documents, all amounts payable by Borrowers under this Agreement and any of the Notes shall be determined as if such Lender had not sold such participating interests, and Borrowers and Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under the Loan Documents. If a Lender sells a participation to a Person other than an Affiliate of such Lender, then such Lender shall give prompt written notice thereof to Borrowers and the other Lenders. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 5.9 unless Borrowers are notified of the participation sold to Participant and such Participant agrees, for the benefit of Borrowers, to comply with Section 5.10 as though such Participant were a Lender.

               14.2.2. Voting Rights. Each Lender shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Loan Documents other than an amendment, modification or waiver with respect to any Loans or Commitment in which such Participant has an interest which forgives principal, interest or fees or reduces the stated interest rate or the stated rates at which fees are payable with respect to any such Loan or Commitment, postpones the Commitment Termination Date, or any date fixed for any regularly scheduled payment of interest or fees on such Loan or Commitment, or releases from liability any Borrower or any Guarantor or releases any substantial portion of any of the Collateral.

               14.2.3. Benefit of Set-Off. Each Borrower agrees that each Participant shall be deemed to have the right of set-off provided in Section 12.4 hereof in respect of its participating interest in amounts owing under the Loan Documents to the same extent and subject to the same requirements under this Agreement (including Section 13.5) as if the amount of its participating interest were owing directly to it as a Lender under the Loan Documents, provided that each Lender shall retain the right of set-off provided in Section 12.4 hereof with respect to the amount of participating interests sold to each Participant. Lenders agree to share with each Participant, and each Participant by exercising the right of

set-off provided in Section 12.4 agrees to share with each Lender, any amount received pursuant to the exercise of its right of set-off, such amounts to be shared in accordance with Section 13.5 hereof as if each Participant were a Lender.

               14.2.4. Notices. Each Lender shall be solely responsible for notifying its Participants of any matters relating to the Loan Documents to the extent that any such notice may be required, and neither Agent nor any other Lender shall have any obligation, duty or liability to any Participant of any other Lender. Without limiting the generality of the foregoing, neither Agent nor any Lender shall have any obligation to give notices or to provide documents or information to a Participant of another Lender.

     14.3. Assignments.

               14.3.1. Permitted Assignments. Subject to its compliance with Section 14.3.2, a Lender may, in accordance with Applicable Law, at any time assign to any Eligible Assignee all or any part of its rights and obligations under the Loan Documents, so long as (i) each assignment is of a constant, and not a varying, ratable percentage of all of the transferor Lender’s rights and obligations under the Loan Documents with respect to the Loans and the LC Obligations and, in the case of a partial assignment, is in a minimum principal amount of $5,000,000 (or $1,000,000 in the case of an assignment between Lenders), in either case unless otherwise agreed by Agent in its sole discretion, and integral multiples of $1,000,000 in excess of that amount; (ii) except in the case of an assignment in whole of a Lender’s rights and obligations under the Loan Documents or an assignment by one original signatory to this Agreement to another such signatory, immediately after giving effect to any assignment, the aggregate amount of the Commitments retained by the transferor Lender shall in no event be less than $5,000,000 (unless otherwise agreed by Agent in its sole discretion); and (iii) the parties to each such assignment shall execute and deliver to Agent, for its acceptance and recording, an Assignment and Acceptance. Nothing contained herein shall limit in any way the right of a Lender to pledge or assign all or any portion of its rights under this Agreement or with respect to any of the Obligations to (x) any Federal Reserve Bank or the United States Treasury as collateral security pursuant to Regulation A of the Board of Governors and any Operating Circular issued by such Federal Reserve Bank, or (y) direct or indirect contractual counterparties in swap agreements relating to the Loans, provided that any payment by Borrowers to the assigning Lender in respect of any assigned Obligations in accordance with the terms of this Agreement shall satisfy Borrowers’ obligations hereunder in respect of such assigned Obligations to the extent of such payment, and no such assignment shall release the assigning Lender from its obligations hereunder.

               14.3.2. Effect; Effective Date. Upon (i) delivery to Agent of a notice of assignment substantially in the form attached as Exhibit H hereto, together with any consents required by Section 14.3.1, and (ii) payment of a $3,500 fee to Agent for processing any assignment to an Eligible Assignee that is not an Affiliate of the transferor Lender, such assignment shall become effective on the effective date specified in such notice of assignment. The Assignment and Acceptance shall contain a representation and warranty by the Eligible Assignee that the assignment evidenced thereby will not result in a non-exempt “prohibited transaction” under Section 406 of ERISA. On and after the effective date of such assignment, such Eligible Assignee shall for all purposes be a Lender party to this Agreement and the other Loan Document executed by the Lenders and shall have all the rights and obligations of a Lender under the Loan Documents to the same extent as if it were an original party thereto, and no further consent or action by Borrowers, Lenders or Agent shall be required to release the transferor Lender with respect to the Commitment (or portion thereof) of such Lender and Obligations assigned to such Eligible Assignee. Without limiting the generality of the foregoing, such Eligible Assignee shall be subject to and bound by all of the Loan Documents. Upon the consummation of any assignment to an Eligible Assignee pursuant to this Section 14.3, the transferor Lender, Agent and Borrowers shall make

appropriate arrangements so that replacement Notes are issued to such transferor Lender and new Notes or, as appropriate, replacement Notes, are issued to such Eligible Assignee, in each case in principal amounts reflecting their respective Commitments, as adjusted pursuant to such assignment. If the transferor Lender shall have assigned all of its interests, rights and obligations under this Agreement pursuant to Section 14.3.1 hereof, then (i) such transferor Lender shall no longer have any obligation to indemnify Agent with respect to any transactions, events or occurrences that transpire after the effective date of such assignment, (ii) each Eligible Assignee to which such transferor Lender shall make an assignment shall be responsible to Agent to indemnify Agent in accordance with this Agreement with respect to transactions, events and occurrences transpiring on and after the effective date of such assignment to it, and (iii) the transferor Lender shall continue to be entitled to the benefits of those provisions of the Loan Documents (including indemnities from Obligors) that survive Full Payment of the Obligations.

               14.3.3. Dissemination of Information. Each Borrower authorizes each Lender and Agent to disclose to any Participant, any Eligible Assignee or any other Person acquiring an interest in the Loan Documents by operation of law (each a “Transferee”), and any prospective Transferee, any and all information in Agent’s or such Lender’s possession concerning each Borrower, the Subsidiaries of each Borrower or the Collateral, subject to appropriate confidentiality undertakings on the part of such Transferee.

     14.4. Tax Treatment. If any interest in any Loan Document is transferred to any Transferee that is organized under the laws of any jurisdiction other than the United States or any State thereof, the transferor Lender shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 5.10 hereof.

SECTION 15. MISCELLANEOUS

     15.1. Power of Attorney. Each Obligor hereby irrevocably designates, makes, constitutes and appoints Agent (and all Persons designated by Agent) as such Obligor’s true and lawful attorney (and agent-in-fact) and Agent, or Agent’s designee, may, without notice to such Obligor and in either such Obligor’s or Agent’s name, but at the cost and expense of Borrowers:

          15.1.1. At such time or times as Agent or said designee, in its sole discretion, may determine, endorse such Obligor’s name on any Payment Item or proceeds of the Collateral which come into the possession of Agent or under Agent’s control.

               15.1.2. At any time that an Event of Default exists: (i) demand payment of the Accounts from the Account Debtors, enforce payment of the Accounts by legal proceedings or otherwise, and generally exercise all of such Obligor’s rights and remedies with respect to the collection of the Accounts; (ii) settle, adjust, compromise, discharge or release any of the Accounts or other Collateral or any legal proceedings brought to collect any of the Accounts or other Collateral; (iii) sell or assign any of the Accounts and other Collateral upon such terms, for such amounts and at such time or times as Agent deems advisable; (iv) take control, in any manner, of any item of payment or proceeds relating to any Collateral; (v) prepare, file and sign such Obligor’s name to a proof of claim in bankruptcy or similar document against any Account Debtor or to any notice of Lien, assignment or satisfaction of Lien or similar document in connection with any of the Collateral; (vi) receive, open and dispose of all mail addressed to such Obligor and to notify postal authorities to change the address for delivery thereof to such address as Agent may designate; (vii) endorse the name of such Obligor upon any Payment Item relating to any Collateral and deposit the same to the account of Agent for application to the Obligations; (viii) endorse the name of such Obligor upon any Chattel Paper, Document, Instrument, invoice, freight bill, bill of lading or similar document or agreement relating to any Accounts or Inventory of any Obligor

and any other Collateral; (ix) use such Obligor’s stationery and sign the name of such Obligor to verifications of the Accounts and notices thereof to Account Debtors; (x) use the information recorded on or contained in any data processing equipment and computer hardware and software relating to any other Collateral; (xi) make and adjust claims under policies of insurance; (xii) sign the name of such Obligor to and file any proof of claim in an Insolvency Proceeding of any Account Debtor and on notices of Liens, claims of mechanic’s Liens or assignments or releases of mechanic’s Liens securing any Accounts; (xiii) take all action as may be necessary to obtain the payment of any letter of credit or banker’s acceptance of which such Obligor is a beneficiary; and (xiv) do all other acts and things necessary, in Agent’s determination, to fulfill such Obligor’s obligations under any of the Loan Documents.

     15.2. General Indemnity. Each Obligor hereby agrees to indemnify and defend the Indemnitees against and to hold the Indemnitees harmless from any Indemnified Claim that may be instituted or asserted against or incurred by any of the Indemnitees and that (i) arises out of or relates to this Agreement or any of the other Loan Documents (including any transactions entered into pursuant to any of the Loan Documents, Agent’s Lien upon the Collateral, or the performance by Agent or Lenders of their duties or the exercise of any of their rights or remedies under this Agreement or any of the other Loan Documents), or (ii) results from an Obligor’s failure to observe, perform or discharge any of such Obligor’s covenants or duties hereunder. Without limiting the generality of the foregoing, this indemnity shall extend to any Indemnified Claims instituted or asserted against or incurred by any of the Indemnitees (x) under any Environmental Laws or (other similar laws by reason of a Borrower’s or any other Person’s failure to comply with laws applicable to solid or hazardous waste materials or other toxic substances) or (y) under any Anti-Terrorism Laws, including any civil fines assessed against Agent or any Lender by any Governmental Authority as a result of conduct of an Obligor. Additionally, if any Taxes (excluding Taxes imposed upon or measured solely by the net income of Agent and Lenders, but including any intangibles tax, stamp tax, recording tax or franchise tax) shall be payable by Agent or any Obligor on account of the execution or delivery of this Agreement, or the execution, delivery, issuance or recording of any of the other Loan Documents, or the creation or repayment of any of the Obligations hereunder, by reason of any Applicable Law now or hereafter in effect, Borrowers shall pay (or shall promptly reimburse Agent and Lenders for the payment of) all such Taxes, including any interest and penalties thereon, and will indemnify and hold Indemnitees harmless from and against all liability in connection therewith. The foregoing indemnities shall not apply to Indemnified Claims incurred by any Indemnitee as a direct and proximate result of its own gross negligence or willful misconduct.

     15.3. Survival of All Indemnities. Notwithstanding anything to the contrary in this Agreement or any of the other Loan Documents, the obligation of each Obligor and each Lender with respect to each indemnity given by it in this Agreement, whether given by any or all Obligors to Agent Indemnitees, Lender Indemnitees or BofA Indemnitees or by any Lender to any Agent Indemnitees or BofA Indemnitees, shall survive the Full Payment of the Obligations, and the termination of any of the Commitments and the resignation of Agent.

     15.4. Modification of Agreement. This Agreement may not be modified, altered or amended, except by an agreement in writing signed by Obligors, Agent and Lenders (or, where otherwise expressly allowed by Section 13 hereof, the Required Lenders in lieu of Agent and Lenders); provided, however, that no consent, written or otherwise, of Obligors shall be necessary or required in connection with any amendment of any of the provisions of Sections 2.3.2, 4.1.3, 5.6 or 13 (other than Section 13.17), or any other provision of this Agreement that affects only the rights, duties and responsibilities of Lenders and Agent as among themselves so long as no such amendment imposes any additional obligations on Borrowers.

     15.5. Severability. Wherever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under Applicable Law, but if any provision of this Agreement

shall be prohibited by or invalid under Applicable Law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.

     15.6. Cumulative Effect; Conflict of Terms. The provisions of the Other Agreements and the Security Documents are hereby made cumulative with the provisions of this Agreement. Without limiting the generality of the foregoing, the parties acknowledge that this Agreement and the other Loan Documents may use several different limitations, tests or measurements to regulate the same or similar matters and that such limitations, tests and measures are cumulative and each must be performed, except as may be expressly stated to the contrary in this Agreement. Except as otherwise provided in any of the other Loan Documents by specific reference to the applicable provision of this Agreement, if any provision contained in this Agreement is in direct conflict with, or inconsistent with, any provision in any of the other Loan Documents, the provision contained in this Agreement shall govern and control.

     15.7. Counterparts; Facsimile Signatures. This Agreement and any amendments hereto may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed to be an original and all of which counterparts taken together shall constitute but one and the same instrument. Loan Documents may be executed by facsimile and the effectiveness of any such Loan Documents and signatures thereon shall, subject to Applicable Law, have the same force and effect as manually signed originals and shall be binding on all parties thereto. Agent may require that any such documents and signatures be confirmed by a manually-signed original thereof, provided that the failure to request or deliver the same shall not limit the effectiveness of any facsimile signature.

     15.8. Consent. Whenever the consent of Agent or Lenders (or any combination of Lenders) is required to be obtained under this Agreement or any of the other Loan Documents as a condition to any action, inaction, condition or event, each party whose consent is required shall be authorized to give or withhold its consent in its sole and absolute discretion and to condition its consent upon the giving of additional collateral security for the Obligations, the payment of money or any other matter.

     15.9. Notices and Communications.

          15.9.1. Except as otherwise provided in Section 4.1.5, all notices, requests and other communications to or upon a party hereto shall be in writing (including facsimile transmission or similar writing) and shall be given to such party at the address or facsimile number for such party on the signature pages hereof (or, in the case of a Person who becomes a Lender after the date hereof, at the address shown on the applicable Assignment and Acceptance by which such Person became a Lender) or at such other address or facsimile number as such party may hereafter specify for the purpose by notice to Agent and Obligors in accordance with the provisions of this Section 15.9.

          15.9.2. Except as otherwise provided in Section 3.1.5, each such notice, request or other communication shall be effective (i) if given by facsimile transmission, when transmitted to the facsimile number specified herein for the noticed party and confirmation of receipt is received, (ii) if given by mail, 3 Business Days after such communication is deposited in the U.S. Mail, with first-class postage pre-paid, addressed to the noticed party at the address specified herein, or (iii) if given by personal delivery or by overnight courier delivery, when duly delivered with receipt acknowledged in writing by the noticed party. In no event shall a voicemail message be effective as a notice, communication or confirmation under any of the Loan Documents. Notwithstanding the foregoing, no notice to or upon Agent or BofA pursuant to Sections 2.2, 2.3, 3.1.2, 4.1 or 6.2.2 shall be effective until after actually received by the individual to whose attention at Agent such notice is

required to be sent. Any written notice, request or demand that is not sent in conformity with the provisions hereof shall nevertheless be effective on the date that such notice, request or demand is actually received by the individual to whose attention at the noticed party such notice, request or demand is required to be sent.

          15.9.3. Electronic mail and intranet websites may be used only to distribute routine communications, such as financial statements, Borrowing Base Certificates and other information required by Section 10.1.3, and to distribute Loan Documents for execution by the parties thereto, and may not be used for any other purpose as effective notice under this Agreement or any of the other Loan Documents. Any notice received by Borrower Agent shall be deemed received by all Obligors.

     Agent and Lenders shall be authorized to rely and act upon any notices (including telephonic communications) purportedly given by or on behalf of any Borrower even if such notices were made in a manner other than as specified herein, were incomplete or were not preceded or followed by any other form of notice specified or required herein, or the terms thereof, as understood by the recipient, varied from any confirmation thereof. Borrowers agree to indemnify and defend each Indemnitee from all losses, costs, expenses and liabilities resulting from the reliance by any such Indemnitee on each telephone communication purportedly given by or on behalf of any Borrower.

     15.10. Performance of Obligors’ Obligations. If any Obligor shall fail to discharge any covenant, duty or obligation hereunder or under any of the other Loan Documents, Agent may, in its sole discretion at any time or from time to time, for such Obligor’s account and at Borrowers’ expense, pay any amount or do any act required of Obligors hereunder or under any of the other Loan Documents or otherwise lawfully requested by Agent to (i) enforce any of the Loan Documents or collect any of the Obligations, (ii) preserve, protect, insure or maintain or realize upon any of the Collateral, or (iii) preserve, defend, protect or maintain the validity or priority of Agent’s Liens in any of the Collateral, including the payment of any judgment against any Obligor, any insurance premium, any warehouse charge, any finishing or processing charge, any landlord claim, any other Lien upon or with respect to any of the Collateral (whether or not a Permitted Lien). All payments that Agent may make under this Section and all out-of-pocket costs and expenses (including Extraordinary Expenses) that Agent pays or incurs in connection with any action taken by it hereunder shall be reimbursed to Agent by Obligors on demand with interest from the date such payment is made or such costs or expenses are incurred to the date of payment thereof at the Default Rate applicable for Revolver Loans that are Base Rate Loans. Any payment made or other action taken by Agent under this Section shall be without prejudice to any right to assert, and without waiver of, an Event of Default hereunder and to without prejudice to Agent’s right proceed thereafter as provided herein or in any of the other Loan Documents.

     15.11. Credit Inquiries. Each Obligor hereby authorizes and permits Agent and Lenders (but Agent and Lenders shall have no obligation) to respond to usual and customary credit inquiries from third parties concerning such Obligor or any of its Subsidiaries; provided, however, that Agent and Lenders shall not disclose any confidential information of Obligors except in accordance with Section 15.17 hereof.

     15.12. Time of Essence. Time is of the essence of this Agreement, the Other Agreements and the Security Documents.

     15.13. Indulgences Not Waivers. Agent’s or any Lender’s failure at any time or times hereafter, to require strict performance by Obligors of any provision of this Agreement shall not waive, affect or diminish any right of Agent or any Lender thereafter to demand strict compliance and performance therewith.

     15.14. Entire Agreement; Annexes, Exhibits and Schedules. This Agreement and the other Loan Documents, together with all other instruments, agreements and certificates executed by the parties pursuant to any Loan Document, embody the entire understanding and agreement between the parties hereto and thereto with respect to the subject matter hereof and thereof and supersede all prior agreements, understandings and inducements, whether express or implied, oral or written, regarding the same subject matter. Each of the Annexes, Exhibits and Schedules attached hereto is incorporated into this Agreement and by this reference made a part hereof.

     15.15. Interpretation. No provision of this Agreement or any of the other Loan Documents shall be construed against or interpreted to the disadvantage of any party hereto by any court or other governmental or judicial authority by reason of such party having, or being deemed to have, structured, drafted or dictated such provision. The paragraph and section headings are for convenience of reference only and shall not affect the substantive meaning of any provision of this Agreement.

     15.16. Obligations of Lenders Several. The obligations of each Lender hereunder are several, and no Lender shall be responsible for the obligations or Commitment of any other Lender. Nothing contained in this Agreement and no action taken by Lenders pursuant hereto shall be deemed to constitute the Lenders to be a partnership, association, joint venture or any other kind of entity.

Nothing herein shall limit the right of Agent or any Lender to bring proceedings against any Obligor in the courts of any other jurisdiction. Any judicial proceeding commenced by any Obligor against Agent, BofA, any Lender or any holder of any of the Obligations, or any Affiliate of Agent, BofA, any Lender or any holder of any Obligations, involving, directly or indirectly, any matter in any way arising out of, related to or connected with any Loan Document shall be brought only in a United States federal court sitting in or with direct jurisdiction over the Northern District of Georgia or any Georgia state or superior court sitting in Cobb County, Georgia. Nothing in this Agreement shall be deemed or operate to affect the right of Agent to serve legal process in any other manner permitted by law or to preclude the enforcement by Agent of any judgment or order obtained in such forum or the taking of any action under this Agreement to enforce same in any other appropriate forum or jurisdiction.

Each Obligor acknowledges that the foregoing waivers are a material inducement to Agent’s, Syndication Agent’s and Lenders’ entering into this Agreement and that Agent and Lenders are relying upon the foregoing waivers in its future dealings with Obligors. Each Obligor warrants and represents that it has reviewed the foregoing waivers with its legal counsel and has knowingly and voluntarily waived its jury trial rights following consultation with
